cant really say on the coil antennas.dont use one. but many like
predator10k.as far as dual not worth it. been there ,done that.tried that.
first off =need cophased 75 ohm coax
second= tuning is very tedious gotta tune them singlely first with
50ohm coax then once tuned .swith to the cophased 75 ohm coax
and check again.never had much luck with them and performance
wasnt even measureable
