At least in a sparse anchorage, u should be able to control all man made emi. Certainly the case in my experience. That leaves lightning crashes for a thousand mile radius. [emoji30]

Yes, u do want to wrap that first turn very low at the post. Keep all bolts in shear. Of course, in the heat of battle, this is not always done. So, the design has to assume high torque loads will...

HF Antenna

I had dreamed of using a weather balloon to hoist a 1/4 wave vertical on the low bands. In settled weather, that may be an option. 160 m would be a short hop daytime or a long hop nite band, I...

Yeah, 60 nm is not far at all. Very early in the program, taking the boynton to WE route, we almost made it, but did run out of fuel. I had to send in a crewman, who towed in an empty prestone jug...

HF Antenna

If 160m becomes real, u will need more wire to let an internal tuner provide the needed inductance to tune.

External amp is also a complicating factor for tuning. Few remote autotuners take 500...

Electrician in FLL

Oh, I just remembered. I worked closely with Island Marine Electric. 401 SE 30 st. FLL
