CyborgAlienWRYG738 Posted 4 hours ago Author Report Posted 4 hours ago Since NOONE is bothering to look, the 2 items are ground plane brackets, that I don't believe I even need, other than to attach a cable at one end and antenna on the other. I asked the question before I wasted anymore money on the Nagoya if the result will be the same, I needed a bracket, similar to the Midland MXTA-23 I believe only without a cable attached to mount the antenna more securely to the top of the 25' flagpole I put it on top of. Having gotten my answer with that, I do still have questions as to why I'm still getting the problem as far as the links, most forums will convert links to photos and since there's so many sad hams here I quit coming here for answers and generally look elsewhere. Not able to find what I was looking for for, I posted in the most logical place to ask my question. Other forums will convert posts to visual of items and even those that don't, most people actually at least click on one to know what they're talking about before even posting comments back. Then sad hams aren't part of those forums either Quote

I'm running a tuned Laird B4505CN on top of it. Tuned using a Laird G8 base. I expected it to be off, I didn't expect it to be off that much. To what do you have the antenna mounted? Quote

Then sad hams aren't part of those forums either I literally clicked on both link and looked at them. That's how I knew what they looked like. You asked, acontextually, which one was best. You gave no context. And then you started insulting the people and software they are running who are trying to help you. Quote
LilRedDog Posted 3 hours ago Report Posted 3 hours ago 1 hour ago, Northcutt114 said: didn't notice that the Nagoya was tri-band. So aluminum is better for tri-band than brass? Why would that be? My point is the two different lengths of the poles make for 3 differently tuned ground planes. I paid no attention to the frequencies the plane offered; it was not easily available. One length is one band, the other a second and combined you end up with the cheaper 20" 'UHF' option. The cheaper one will work but you have no ability to trim/tune it on the plane. That is assuming Nagoya has the assembly for each band somewhere. You can guess around 8" is GMRS if nowhere else to start and try the other one for best SWR. I doubt 20" is optimal for any GMRS antenna. There are reasons, I'm not getting into, why this is not as much an issue on a car but I will add moving the magnet around is enough to 'tune' the plane on a mostly-flat metallic surface >8". Edit- For some reason I referred to the other one as cheaper when it is $10.00 more. Does not change my 'opinion'. SteveShannon and Northcutt114 1 1 Quote

CyborgAlienWRYG738 Posted 3 hours ago Author Report Posted 3 hours ago Images of what I have, the Browning LMR-400 cables are a 25' run down the inside of the pole to a lightening arrestor in the ground attached to a 50' to the Radio. Currently, I have the Midland MXTA-26 antenna on it, trying to see if any difference in SWRs, maybe .1-.3 difference. Quote
LilRedDog Posted 2 hours ago Report Posted 2 hours ago 5 hours ago, CyborgAlienWRYG738 said: I got the Tram one, when all was assembled, it's getting 4.6+ SWR, I was curious if it was maybe it being defective or what's the possible cause of the problem, reason for my initial query. I'm sorry: the thread went off the rails and i missed this information. It's, probably, too large. You can try sticking in rods that fit, they can even droop a bit, and try shorter lengths. Seriously: If you can cut a coat hanger and if it will fit, not strip threads and not droop much, the field will not know. It wont last but you can experiment. Quote

Do you have an antenna analyzer that will sweep the range from 462 to 468 MHz so you can see where the minimum SWR ratio occurs? Maybe the antenna just needs tuning. Quote
