First, I want to thank everyone in advance for any advice, guidance, or help concerning tuning.
Here's what I have:
2006 Jeep Wrangler
Uniden 520XL
102" whip antenna
Astatic PDC7 swr meter
18' coax cable (could be 12')
My antenna is mounted to my bumper with a heavy duty spring and the coax runs under the bumper, up the fender and then routed through the padding of the roll cage.
I connect my swr meter to my CB and start with channel 1 in the FWD position and adjust the needle until it is on SET. Then I switch to the REF while continuously transmitting. The needle remains in the red with something like a 3.5.
I change the channel to 40 and repeat the same process above and I still get the needle in the red with something like a 3.4 or 3.5. Its so small in the change you really can't tell.
I do know that if one reading is higher than the other then it will dictate your next actions, lower or shorten the antenna. However, I can't seem to find the reason why I'm in the red to begin with. Additionally, I am wired into my fuse box with a connector and grounded to the floor.
Any help in this matter would greatly be appreciated. Thank you
