Do you use a balun at the antenna

Good RF chokes on the coax at the feedpoint and at the point of
entry would go a long way to eliminating any "RF in the shack"
problems. A couple 2.4" 31 mix cores with half a dozen turns on
them, for instance.

Whether the V is tuned or not won't have any effect on RFI or grounding.
A BalUn would help a lot.
Balun/choke.. tomato, tomato.. they're really all the same thing.
Keep the RF off the outside of the coax.


Since we are sticklers for the NEC, Homey needs a #6 wire from where
the transmission line enters the dwelling to an 8' copper clad rod
driven into the earth, as close as practicable.

Turns out he's located in Germany, so U.S. codes aren't particularly
relevant. If anything, German codes are probably stricter. But almost
certainly different.

Yes indeed. It's not like there's any universal consistency in the U.S.
either.

I recommend IEEE Std 1100 for people who really care. (and it is an
international standard, so it addresses most of the regulatory issues
regardless of location)
