Using anything heavier than #12 is a waste of effort, money, and height. As for the radials. They never hurt, and would probably help, but, imho, not worth the extra effort. As for 'lifting' a groun

Pet containment systems do NOT pulse. They are simple a low-power transmitter of continuous output which the COLLAR worn by the pet picks up and then switches on a mild shocking to the pet. Don N8DE

You will get different answers from different people depending on their success or lack of it with RG8X. My experience: Used a 100'+ run of buried RG8X to feed a 3-element vertical array on 40m using

I wouldn't put more than a TV antenna on that tower. Looking at the 'bracing' between legs, it looks very weak and a rotational torgue might twist the entire tower. There is NO cross-bracing. Not one

Roger, I've had good success using the double-core balun kit Wireman sells. Not sure why you'd have 3:1 to 4:1 SWR for a well-designed antenna, though. Make the balun 4:1 and it should play forever.
