Why don't you try a 150' BOG? I know a guy in Maryland who has one only 140' long, and he hears DX on it on 160 that he doesn't on his inverted-L. Probably better than a BOG is a Slinky Beverage. 73,

My 160 inverted-L support rope broke, Bill. And there are other issues. (Long story.) When I am able to put it back up, it will absolutely have Guy's FCP instead of the two elevated radials like I ha

I agree with Jim. Beverages don't have to be ideal to work very well indeed, thank you. It's the matching transformers (and maybe their grounds) that are a more important thing to worry about. You ne

Hi Tom, I'm not saying it's a good idea, or that anyone should. :-) I'm just asking, What might happen if water got in there, wicked along the inner braid, causing corrosion? My gut feeling is that s

Does there always need to be electrical continuity between the various shields along the length of coax? I don't think so. According to https://awapps.commscope.com/catalog/broadband/product_details.
