Got my antenna up and running after about 20 hours worth of work (not including Home Depot trips).
First I want to mention the performance was better than I had hoped for. Very happy with that. Yesterday had a long chat on a repeater that I wasn't even expecting to hit.
The second thing Is the the SWR was 1.5 on Medium power from my BTECH 50x1 and and 1.3 on low power. I would like to improve on this.
I'm using 33ft. of Times MicroLMR-400 coax with Amphenol PL-259 and Time Micro N-male connector. The #4awg ground rod wire is about 4ft long. The antenna is about 5 ft. over the top of the roof line. I'm using a Diamond 400 SWR meter.
The instructions said to use either 1 or 2 loops for the rf choke. I made one loop. The radials have a VERY small adjustment of about 1/4" on all 3. I set the radials in as far as they would go and tightened things up. So I could extend them a bit.
Would adding another loop to the rf choke help and would lengthening the 3 radial make a difference?
Any advice would help.
I forgot to mention that I tested the SWR on all the GMRS and GMRS repeater frequencies and they where all very close in measurement.
Thanks guys for all your help.
