[Elecraft] BL-2 Connection To An Unbalanced Wire Antenna

[Ron D'Eau Claire]

Of course it is Jim! It's a relatively (35 ohms, thereabouts) impedance.
That's a decent RF ground, especially when compared with no ground. 

It's *not* a lightening ground.

It's *not* a mains power ground. 

But it *IS* a ground for RF purposes, just as the radials on a ground plane
ground are an "RF Ground", meaning a low-impedance path for RF currents to
flow.

That's not an "RF ground," it's a counterpoise, it's radials, it's the other

half of the antenna. I agree that what you've described is very important to

make the antenna work, but it's NOT "RF ground."
