Hello Vinnie:
If that antenna doesn't work, maybe a out side stealth small gauge wire vertical dipole will work great, if you have some tree's around.

I got my setup running, but have a high SWR on the CB band. Here are the parameters: My SWR is 1.5 on channel 1, and 3 on channel 40. 1. I have a a 6 foot Firestik in the attic. I am using 8 pieces of 10 gauge wire, all 102" long, as a ground plane connected to the mounting stud. 2. The mounting stud and ground plane wires are not connected to earth ground. There is no way I can get a ground rod into the frozen ground. Not at least for a few weeks. 3. I am using 50' of LMR-400 coax. No shorts measured. 4. I have a RF choke/balun of about 8 turns, 8 inches round, about 2 inches below the antenna and ground plane wires. I cannot get it any lower. 5. The radio is a HR-2510, and that is not grounded for the same reason as #2. I did a frequency check to see where this antenna is tuned. It seems to be tuned for 26.500-26.800 MHz. The SWR is a flat 1.2 across that band. It starts to when I go below or above that band. I wanted to know if there is anything I should do before I cut the wire on the Firestik. Would grounding the ground plane or the radio to a ground rod help? And suggestions are appeciated. Vinnie S. |
