I don't have a choke on the sloper feedline, but I did run the coax inside the Trylon tower legs into a steel box at the base where the antenna switch is. I'd often thought about shortening the wire for 60M and installing a loading coil and shorting relay at the coax/wire junction for 80M operation, but haven't convinced myself to go through the trouble. 73 de Gene Smar AD3F

Is a CM choke required at the feedpoint ? If I can't fit the entire required length of wire,(I think I can get aprx 110-120') can I insert a small coil at the feedpoint ? Perhaps relay switched, to obtain 2 x segments. I'm toying with the idea of using the 75m rotary dipole at the top of the mast as a possible RX ant for 160m....might be worth a try at least. The CM choke at the 75m rotary dipole has 10.5 k Z on 160m. I have zero room for dedicated 160m RX ants. My corner lot is only 89' wide x 115' deep. Monster house next door. I have a power line running down the side street, on my side. Jim VE7RF On Sat, Jul 27, 2024 at 12:50 PM Felipe J.
