VWINME Posted March 10, 2011 Share Posted March 10, 2011 Can anyone get hold of the specs for Ptarmigan Radio Antenna? Frequency etc. NSN 5820-99-647-9537 Also could do with some specs on 5820-99-652-8219 Thanks in advance. Russ Quote Link to comment Share on other sites More sharing options...
diver99 Posted March 10, 2011 Share Posted March 10, 2011 Have you emailed the Signals Museum. They have volunteers who are excellent with info and details. Quote Link to comment Share on other sites More sharing options...

g0ozs Posted March 14, 2011 Share Posted March 14, 2011 Hi The radio links for Ptarmigan were called Triffid - see: http://www.armedforces.co.uk/army/listings/l0085.html#TRIFFID Trifid UK/TRTC-471 itself was a Siemens product adapted for UK use by Marconis: http://www.armyradio.co.uk/arsc/customer/product.php?productid=1517&cat=0&page=8 http://adsabs.harvard.edu/abs/1981mimi.proc..129D http://www.ekmpowershop5.com/ekmps/shops/greenmachines/uktrc-471-triffid-radio-station-illustrated-parts-list-1133-p.asp Band I was 225-400MHz, Band II was 610-690MHz and Band III was 1350 to 1850MHz. So the antennas dont seem like a good match to either the 70cm (430-440MHz), 23cm (1.3GHz) or 13cm (2.4GHz) amateur bands Hope this helps Iain Quote Link to comment Share on other sites More sharing options...
Stone Posted March 14, 2011 Share Posted March 14, 2011 Band I still has good coverage of military airband though. The RF cables on TRIFFID cabins (usually attached to their MJ at Withams) are pretty good quality for ham use - and the strange connectors can be adapted to N-types with the bulkhead sockets. I've still got all sorts of bits kicking around from ours... Stone Quote Link to comment Share on other sites More sharing options...
