Jeff, Wow, nice set up, but of course, a few questions and comments....
Is there any way to get the base (feed point) of the antenna portion above the top of the RV? Do you find that the 991 matches the antenna on all the bands it is purported to work on? Probably not, cause it shouldn't on any band. This antenna is a classic marine type installation that is made to work in conjunction with an antenna coupler, right at the antenna feed point. The system -- coupler and antenna is very dependent on some type of ground/counterpoise. These extra wires should be run out of the coupler's ground stub. But before I dive off into telling you intimate details as to how it all should be hooked up, I encourage you to give yourself a bit of an education SGC -- the mobile antenna system folks have a few technical articles and pamphlets that I encourage you to read. Go to SGCworld.com ..click on Publications and then near the bottom of the list HF USER Guide Also, https://www.sgcworld.com/smarttechnote.html tuner versus coupler article. Plus there are a crap load of white papers all about mobile/portable HF installations. You'll be reading for weeks. HI HI There are a plethora of ways to make this system work and work well, but it entails adding counterpoises/radials/top loading wires, etc. I know you can get this down to a minimal deployment set up, so you are not having to reinvent the wheel each time you park your RV. It just takes knowledge and time to fine tune it to your requirement. Best of luck and I am available to discuss things further, if you see a need. 73...Rick -- W5RH On Tue, Sep 28, 2021 at 10:34 AM Jeff Thomas via BVARC <bvarc@bvarc.org> wrote: > All, > > Looking for some antenna advice.
