***UPDATE***
so, I was wrong about that stryker whip being $30, its actually $19.53! that aside, the guy i told you I found in Genesee co, MI, emailed me late last night and said IF I could be at his "shop" by 1pm today, he'd give me 15 minutes of his time! so, I made it by 1245!! 1st thing he said was my antenna was a bit to far back!! he then told me that because I have a fiberglass topper, magnetic mount antennas need to be "slightly" further forward for reflection purposes! so, I moved it forward exactly 8 inches. while was doing that, he took my 29ltdnw and put it on his equipment. RESULTS- my radio is "good", HOWEVER, it was missing a few "things", like another pot!! pls forgive me for not knowing what all he said, as he told me, 15 minutes, and I was on my way in less than 25 minutes!! as you, and others have said, I didn't buy my radio from cobra! and he showed me what you(or someone) said aboot "cobra electronics" NOT being cobra!! with that being said, he showed me a 29ltdnw he had in his stash and showed me where there was "supposed" to be 2 other pots, his had em, mine didn't, and his was, from what i couldtell betweenthe2, all stock! so, shorten this up, he said by me crankin up the modulation pot I actually did more "harm than good"! and, same with the antenna warning pot! again, I don't remember what all he said, remember, I had 15 minutes of his time!! so, he reset the mod pot to factory, and gave aboot 1/8 of a turn more. POWER TEST- aboot 2.6-2.8 at best!!! he inspected my antenna cable routing, PASSED! he inspected my wiring, PASSED! he measured the antenna distance from my topper, PASSED!! we put radio in, set swr, which BTW, needed another 1/4 cut as swr was a "tic" higher on 40 than 1. swr on 1-20-40 aren't even moving off 1, and thats on his, and MY swr meter(s)!!! BTW, the final drive in the 29lx is bad!! but NOT in the 29ltdnw!! so, with everything all hooked back up and swr readings "great", I keyed the mic AND.....BOOM, my voice was "heard"!! from his vehicle, aboot 50 feet away, which actually had the radioddity QT60 in it with a Wilson 5000, he heard me loud and clearly!!!!!!!!!! so, I moved to another channel, called out a "mic check" and, I got a response!!!!!! so in closing, im on the field!!! now, he did say I'd be "incredibly lucky" IF i could catch anyone more than 5 miles away, on a clear sky night! since its so under powered, he said highway driving I'd be able to reach out 2-3 miles, maybe 4 if no obstacles like trees etc!! he quickly explained the location of magnetic mounted antennas to me, basically unless I repainted my topper with metal flake paint OR cover the top of it with tinfoil tape, something aboot reflection wasn't good or was to much, idk, or actually remember but by moving the antenna forward away from the topper and more towards the hood definitely helped!! side note, I called my buddy and ask him about his antenna location, he measured it and it's aboot 3 inches "off center" BUT, his RAM 2500 is the "mega cab"(dodges version of Fords supercrew) so that made a bigger difference according to the guy helping me!! sooooo, im a step closer!! now I just gotta get a better radio!! and, as he said, it'd cost me aboot the same money to buy the radioddity QT40 as it would to have him rework my 29ltdnw, but he HIGHLY RECOMMEND i just buy the QT40 and then decide what to do with the 29ltdnw and 29lx!! so, im hearing voices a bit clearer AND, at a closer distance, my voice is being heard!!! NOW, he said I "might" have to buy another whip for my antenna IF I buy the QT40! but im good using it on the cobra and the swr readings are perfect!!! keep ya posted WHEN, not IF, I get the QT40 👍👍👍
