I'm thinking of cheap or improper coax (50 vs 75 ohm), or bends that mess up the outer shield/braid. But you're right, if none of those are a problem, then measuring SWR before or after feedline won't matter.

Using 75 ohm feedline on a 50 ohm output would make the SWR at least 1.5 right off the bat!

Instead of hijacking OP's thread and arguing about geek-speak, here's some links with real peoples' SWR results for tail-light mounted antennae:

(dfry Reports 1.2):

(tchaap reports 'very low'):
http://www.wranglerforum.com/f5/cb-a...ml#post1009318

(Tombo reports 1.6 to 2.8):
Cooltech Ultramount SWR help/suggestions

I think that the moral of the story is "2-3 is common but ok, less than 2 is good but harder to get"

Sorry, I didn't see where there was any arguing...

Why even bring that up? No one was talking about using 75 ohm coax any more than we were talking about using ac cord. Oh I forgot this is the internet.

Hey here's a post where cjnut claims either 1, or 1.1 with a tail-light mounted firestick:
http://www.wranglerforum.com/f5/cb-a...ml#post2179903

I'm surprised a whip mounted there could get such a low SWR. In retrospect, I probably didn't need to do my custom mount...

I just installed my new swing away tire carrier from Groundpounder Fab. I had Eddie install a plate (per my design) on top of the swing away for a CB antenna and brake light. Here's what we came up with. I'm very happy with it.
