extremely high SWR and won't work

[Firekite]

Wondering if this bracket mount was more intended for mounting lighting or sand dune flags.

Great point. He did link to the product, and it is marketed as a CB mount, but it’s from a company that mostly lighting and accessory brackets and mounts, not a radio shop. I have a feeling it could be as simple as someone going, “Hey, don’t CBs use a 3/8” mount? Sell it as a CB mount!” And the other dude said, “Hey, yeah, you’re right! Done!”

It also could’ve just been a bad production run where someone got confused and used a 3/8” bit instead of a 1/2” bit in the jig, and no one noticed. Assuming it’s not all CNC/laser/water cut. The web page doesn’t provide any specs at all, so who knows?

By the way, I just called them and left a message to let them know they need to have a 1/2” mounting hole instead of 3/8”. They’re near me in Kerrville, TX, as it turns out.

That is what I like about this form folks helping folks and all the great info on the site.

I don't mean to resurrect a dead thread, but I'm curious if you ever got this figured out. I'm having some slightly high SWR issues on my mobile as well, and it seems like we may have similar problems. Also, if you haven't already tried it (hopefully I didn't miss somebody else recommending this), try removing the spring and seeing if that helps.

Hi, hope I can get some help with a similar issue. Cobra 75, firestik 4' antenna with firering coax. I've tested for continuity and everything is fine EXCEPT when I plug the coax into the CB radio. When I do that I suddenly get a closed circuit with about 4,700 ohms of resistance between the mount and the stud. If I unplug the coax from the CB the resistance goes back to infinity (open circuit). Is that normal? I don't think it is... I'm wondering if this radio is damaged. I purchased it as a used radio via eBay.

I'd really appreciate any help. When I hook everything up my SWR reading is about 2.5 and it fluctuates. I have tried tuning the antenna but no improvement.

The 4,700 ohms is the static drain off resistor in the radio. So that part seems OK.

Did you try a different radio in your setup?

no, I only have this one. So you say the 4.7K ohm reading is normal? Hmmmm I really thought that indicative of an issue with the radio. Ok I will go over everything again and report back. Thanks very much for the quick reply.
