Wellington Bomber D F Aerial and Control box (pg 2 rad)

 

This  DF aerial and control box, rate as one of the rarest parts, you will see on this site. Made by the British company Marconi, this Bako case and DF aerial was being used operationally in 1939 and 40. It was fazed out shortly after and replaced with another material. It was important that no magnetic source was present. The unit was a radio compass and helped the Wellington find its way to the target and home again. The DF aerial rotates mechanically when the knob on the control unit is turned. They are connected by a Speedo type cable. I am hopefully collecting a cable shortly and this will be included in the sale if it comes off. At present the items for sale are as seen. The aerial can clearly be seen fitted to the top fuselage just behind the cockpit of the famous Wellington. A copy of a some technical info will be sent with the item.

D F Aerial (pg 2 rad)

This  DF aerial has unfortunately had a hole cut in it, it also has some cracking around the nose. Someone with the right skills should be able to effect a repair good enough for static use.

I believe these aerials were used in other bomber types including the Halifax and Lancaster

Reserved

An extremely rare Rebecca Yagi aerial in superb condition designed to be mounted with an accompanying identical but handed aerial on the nose of the carrying aircraft. This item was undoubtedly carried and saw service with an RAF aircraft and is of the design used by Bristol Beaufighters as well as Lancasters as shown by the paxolin screens which were incorporated to prevent propeller modulation interference and give a measure of torsion rigidity.

Rebecca Aerial AN-148 Lancaster/Beaufighter (pg2 rad)

Rebecca / Eureka is a simple system designed initially at the behest of SOE to assist in the delivery of supplies to the Army, and Resistance Partisan groups in occupied Europe and came into use during 1943. Later, the system expanded into blind homing and approach aid for aircraft. . It consisted of two parts, the Rebecca airborne transceiver and antenna system, and the Eureka ground-based transponder.

The Rebecca code name was derived from the phrase "recognition of beacons". Rebecca calculated the range to the Eureka based on the timing of the return signals, and its relative position using a highly directional antenna. The airborne Rebecca interrogator transmitted a 4-5 μsec long pulse at a rate of 300 pulses per second on a frequency between 170 and 234 MHz. Upon receiving this signal, the Eureka rebroadcast the pulses on a different frequency. The Eureka unit also included a keying system that periodically lengthened the pulses over a period of seconds, allowing a Morse code signal to be sent for station identification.

This rebroadcast signal was received by two directional yagi antennas on the aircraft carrying the Rebecca unit. The signal was then sent to a conventional ASV radar display, with the vertical axis measuring time (and thus distance) and the horizontal showing the strength of the signal. If the aircraft was approaching the Eureka from the side, the horizontal pulse would extend further on one side of the display than the other, indicating the need for the aircraft to turn toward the shorter blip in order to fly directly toward the Eureka.

Lancaster T.1154B Radio (pg 2 rad)

A classic original T.1154 radio transmitter used in Lancasters as well as high speed launches. The Lancaster was not the only aircraft in which this equipment was installed. They were used extensively in aircraft of all types in the RAF during  WW2.

TRANSMITTERS, Types T.1154, T.1154A, B, C, D, E, F, H, I, K, L, M, and N

Avro Lancaster


Transmitters of the T.1154 series were designed primarily for installation in aircraft, to provide air-to-ground or air-to-air communication by W/T, and in all but two versions by .R /T as well. Series L, however, was intended for installation in high-speed launches, and series D and E were introduced for mobile ground stations. Normally all these transmitters were used with receivers of the R.1155 series'

The aircraft version had an aluminium case for obvious reasons where as the marine version had a steel case.

This version is for aircraft use as it has a Aluminium Case

R.1155 Radio receiver (pg 2 rad)

The R1155 is an English LF and HF superheterodyne receiver covering from 75kHz to 18.5mHz in 5 bands, with D/F (Direction Finding) and homing functions. This receiver started development in 1939 by the Marconi Wireless Telegraph Co and was called the AD.87B/8882B to replace the pre-war T1083 and R1082. The R.A.F. designation was the R1155 and the  corresponding transmitter was the T1154, the first units being installed in June 1940. These were still used into the 1950s. Several companies manufactured them, including Marconi, Ekco, Plessy, Philips, and the Gramophone Co. (EMI). They were fitted to many aircraft like the Avro Lancaster and the deHavilland Mosquito.

Supermarine Seafire R1147B (pg 2 rad)

A/M 10D/13129

Very good condition and  complete R1147B.

Radio Receiver used in the naval variant of the Spitfire the Seafire. Aiministry crown so pre 1944 manufacture. Very rare looks to be in serviceable condition although I would not know how to test it, complete in original transit case. The frequency knob is removed for transit but is included. It also comes complete with its mounting tray. This receiver is tuned with a winding handle inside the LHS of the Seafire cockpit  You can read more about radios on page 10 reference section.

As early as 1938, Supermarine had approached the Admiralty with a specifically designed Naval version of the Spitfire. However, due to circumstances beyond their control, the Admiralty ordered the Fairey Fulmar as the new aircraft of the Fleet Air Arm. In February and May 1940 the Admiralty asked the Air Ministry for Spitfires but on both occasions they were turned down. However, with the Admiralty's need for a capable carrier-based fighter to take up the task of combating Japanese Zero's or Messerschmitt  the Seafire II could perform that task, this need eventually led to the Fleet Air Arm being provided with the modified Spitfire land-based fighter to take up the combat roll. In 1941 the Air Ministry offered some Mk I Spitfires to the Navy but the Admiralty demanded the latest version in production, the Mk V.

GEE Radar Set (pg 2 rad)

Click on he picture's left to enlarge

An immaculate Wartime Gee set with Kings Airministry crown. In very good complete condition. The only issue is ha the Gain button has been snapped off but this should not be to hard to rectify.

Type 95 A/M 10Q/16

GEE was a navigational system that utilised accurately phased pulses from ground based transmitters and it was the brainchild of R. J. (Bob) Dippy, who first set down his ideas on paper in 1937. However the rush to get the Chain Home system operational meant that Dippy's paper lay forgotten until 1940 when an urgent need for Bomber Command to have a reliable system of navigation arose. Dippy's system became operational in early 1942.

GEE was highly effective and accurate as an aid to navigation, but it lacked the pin-point accuracy needed for a bombing attack on a selected target. A British scientist named Alec Reeves rose to the occasion and developed a through-the-clouds bombing technique known as OBOE. Although developed in spite of the earthy comments of doubting-Thomas detractors, OBOE proved to be the most successful of all such techniques developed during World War II. By mid-1944 the principle of OBOE was combined with GEE and a blind bombing technique known as GEE H was developed. Strikes upon difficult-to-hit targets were made by the RAF and the USAAF and Hitler’s war machine was badly crippled by a lack of petroleum products and sorely needed replacements.

R1082 R1155 WW2 RADIO RAF  BOMBER MONITOR (Pg2 Rad)

An opportunity to acquire a rare Crystal Monitor Type 2, a useful piece of kit designed for use in aircraft to facilitate the initial adjustment and subsequent monitoring of CW transmitters and receivers. It enabled a rapid and accurate shift of operational frequency to be made and a convenient method of making the necessary adjustments for the correction of frequency drift, which could occur during flight.  The monitor operated any one of six spot frequencies in the range from 7.5 m/cs to 1 m/c. 6 quartz crystals for the appropriate frequencies are fitted in the monitor and a seventh or extra position is provided on the panel of the instrument. Any one of the crystals could be utilised by a rotary switch on the front panel. The monitor was powered through the receiver's HT and LT batteries. Used in both the T1083/R1082 and R1155/T1154 radio/wireless operators set-up. These sets were introduced to the RAF in the late 30's and early 1940's and would be used in a wide range of operational aircraft throughout the war. Amongst the photographs is an example of the monitor in situ in a Wellington set-up for illustration purposes. The approximate dimensions of the unit are approximately Width 180mm x H110 mm x Depth 125mm. The cabling and plugs illustrated are included. It weighs less than a Kilogramme. The set appears to be in original condition and I found no evidence of restoration.

See in situ in a B17 under.

Type W1191A A/M 10T/565

Other special equipment utilized in the Gremlin's bag-of-tricks were powerful electronic jammers. These devices had unusual nicknames like Mandrel, Dina, Jackal, Jostle, and others. Mandrel, for example, was an airborne transmitter tuned to radiate noise over the enemy radar frequencies. This disturbance tended to obscure the size of Allied attacking forces on the enemy's radar screens and also caused the enemy to conclude an attack was imminent when one was not. Another airborne electronic jammer, nicknamed Jackal, was used to jam the German tank communications during the Battle of the Bulge in the winter of 1944-45. Many of the aircraft jamming systems were developed and tested by Allied scientists associated with the American-British Laboratory Division 15 (ABL-15). They were part of the British Telecommunications Research Establishment located at Great Malvern.

This is the winch for a trailing aerial as fitted to Lancaster's and other heavy bomber's. In excellent condition it still function's perfectly.

For reception of communications signals, the receiver could be operated with either fixed or trailing aerials; a fixed aerial was normally used for the HF ranges, and the trailing aerial for airborne installations on the MF ranges. The trailing antenna mount, just below the leading edge on the port side of the Lancaster. The 'bobbles' are lead weights on the end of the antenna wire.

GEE and H2S Radar Choke box and Control panel (pg 2 rad)

Superb original Wartime power unit and choke as connected to H2S and GEE in the Lancaster's Halifax and the Sterling. Internally complete and original.

Below extract from an AP manual

The picture below is a set up  just for GEE the, above set is for GEE and H2S

H2S’ became available in January 1943 and was regarded at the time as astonishingly advanced. Kept top-secret for as long as possible, large bulges began appearing under the bellies of some heavy bombers. Inside was a rotating parabolic dish which mapped the ground beneath, even through cloud, onto a screen in the aircraft. The fairly blurred picture on the screen differentiated between dark areas for sea, bright areas for land and very bright for built up areas. It worked best on coastal targets or those with a broad river or lake nearby. At first, the new H2S sets were installed only in Pathfinder aircraft who flew ahead of other bombers to accurately mark the target with coloured flares.

The first major development in navigational technology was ‘GEE’, a system perfected in early 1942. An on-board set received synchronised radio signals transmitted from ground stations in different locations in England. Two signals gave the navigator a ‘fix’ so he could work out his aircraft’s position on the route to the target at any time.

When flying near the ground stations over home territory, GEE’s accuracy was good; At increasing distances, particularly into Germany, accuracy was reduced. However, with a range of about 300 miles, GEE at least ensured that each bomber crew entered enemy territory with reasonable confidence as to their position. After a time, the Germans worked out a way to jam the system (i.e. interrupt the radio signals from England). British scientists were forced to develop new GEE systems, new frequencies and jamming of their own.
