Re: [TCML] RF Ground and Brass
Hi Phil,
(how do I get involved in these things? must be my big mouth)
But on the other hand, if the grounding wire has too high an RF
impedance, it won't be carrying much current in the first place and therefore won't
even have a chance to get warm. By the same thinking, a piece of nylon fishing
line makes a fine ground wire.
The base carries several amps of current and a low voltage drop. Should
the wire be sized for the load? Yes. Should you use nylon line? No.
The easy test is probably just empirical. Just keep increasing the
expense of the ground connection until you get a diminishing return on
performance. In my experience, 10 feet of 10ga stranded copper works fine.
10 awg would likely do fine even over a decent length.
Take care,
Bart
