Rich,
I often eliminate the feedline by using an EFHW antenna or random wire antenna.? I use the K6ARK kits which build the balun right onto the BNC.? No feedline. When I do use coax (dipole or vertical), I keep the coax as short as possible, and use RG-316.? But I'll admit, I'm more often working SOTA than POTA, where lightweight gear is more necessary.?
