As for antennas I ise a multitude, mainly I use a end feed piece of wire, I also have a full size g5rv and a home made buddy pole which has coils for 15/17/20 meters and works well on 10 & 2. The end feed wire I use most is a piece cut to about 14 meters and connected to a 9:1unun. I also use a sota beams end feed cut for 20meter band with a homemade 4:1 balun. Any other questions feel free to ask
Nice to see a Go box from a fellow D2 owner ! Have made a first attempt at something similar (not as sophisticated) using a small Stanley tool box that sits in the right rear corner having removed both the rear folding seats for extra storage space. Will try to post some pictures when i get time & work out how to !!
