    My B6TV mount on my dock over salt water

    Hi All, I have a 6BTV antenna mounted over salt water on my dock. I wanted to share a video about the installation, and a video about the real world performance of my vertical antenna. This antenna does not feel like a compromise to me. 73 All, Paul

    Distance between Ham antenna and Diamond Super Discone antenna for Scanner

    I am thinking of getting the D130NJ Diamond Super Discone antenna for my Uniden BCD996P2 scanner. My father already has a roof-mounted ham antenna up that he regularly transmits 100 watts out of. The question that I have is, how far should the discone antenna be mounted from my father's ham...

    MFJ 2100 Octopus

    i'm considering an MFJ2100 Octopus on top of a fence top rail as a mast... not sure how durable it will be when left outside long term, or how well it will work with my MFJ939 tuner... i originally wanted to get the CHA Spider, but they aren't currently being made and Chameleon says they won't...

    Discone Scanner Antenna Near 100 W HF Dipole

    So I recently updated my scanner setup and installed a Comet wide band discone on my roof connected to an SDS-200. I am also a ham and operate a lot of FT8 at 100 watts on 20 and 40 meters from a dipole antenna located about 15 feet from the discone. I've noticed if I am monitoring the scanner...

    NMO Mount with Factory Roof FM Antenna Hole

    Hi all, Yesterday, I was looking at my ugly mag-mount U/V antenna I have on my trunk (2008 Ford Fusion), and had an idea. I don't use the AM/FM or Sirius functionality in my car (my phone has all the music I'll ever need), and I've already purchased a stubby replacement antenna mast for the...
