- Just to correct the comment by John Sallis (whose shop in Brighton I used to buy from in the early 1970s!)
I am sure John is right that this ground plane assembly was used with the R109 - but the transmitter that went with it was not the No.17 (which is a VHF transceiver used by anti-aircraft batteries during WWII) - but rather the Wireless Set No.76. The significance of the WS76 is that it was used (with the R109) during the famous Battle of Arnhem. It was probably the only radio used at this battle, which actually worked as intended.....

- This ground plain assay had nothing to do with the WS19, this assay was part of the Reception set R109 which was a man pack receiver 1.8 to 8.00 Mcs 6 volt valve line up ARP12 RF and 1st and 2nd IF AR8 Det and Audio
This asy was all part of the R109 kit which inc 2 pair DLR5 headphones, 2 carriers, earth rod,small operators light with 2 pin plug power lead,operators book and about 3 lbs of silica gell
The other half was W Sender no 17
