When and where to ground is not as simple as it sounds at first thought.? Depending on circuit design, several grounding schemes for microphones might have to be tried to ensure proper shielding while at the same time not creating a ground loop.? Too, ferrite beads on each and every lead going

For years I have used a trapped inverted Vee using Reyco 40M traps and a W2AU balun. Works great on 80M and 40M and will work other bands with a tuner. A good antenna. Also, no matter what they say, The G5RV at 102 feet long is a fine performer on 80, 40 and 20 for sure. Do not sell it
