Do you want to get on the nets while underway or on the hook or both? On the hook, nothing beats an inverted-vee dipole hoisted up the mast
with each leg as close to 90 degrees as possible, then no tuner needed. Using coil and cap traps, this will work on as many bands as you build or buy the traps for. That is what I use and have (2) fiberglass
telescoping 40' poles angled on opposite railings. Underway you could use a vertical whip tuned to your operating frequency, i.e 14.300 mhz would be 468 / 14.3 / 2, for a 1/4 wave antenna. 16' 4 1/2". You will need to run a counterpoise
for this antenna if used without a tuner.
