Galaxy DX 939 w/Wilson "Lil Wil" antenna in a Toyota Tundra:
Since I swapped out a lousy cheap antenna from Wal Mart for a Wilson "Lil Wil" the SWRs, or should I put it, I can't get bad SWRs with the Wilson. Little under 1.5 on 1 and 40, and little over 1 on Ch. 20. My power meter hits 8 on Ch 20 just keying the mike. Am I doing this right?
I learned quite a lot here in the past week just snooping around, plus from a renowned cb shop in Ontario, CA.
A thought occured to me about my ground plane on the roof of my Tundra. My Tundra is white as is the camper shell, and white usually contains Titanium as a dioxide, a metal. I know the shell is fiberglass, but I wonder if the paint on the shell serves as a metal ground plane?
Edit: Possibly ferrous material in the dirt on the roof might be enhanceing the ground plane?
In the photos, you can see I mounted the radio in the Center console. When folded up it serves as a seat back with a headrest. I pulled out the headrest, re=drilled some holes on the mounting bracket and got some expanding lugs that fit where the headrest goes in. Feels solid enough.
Should I be happy?

Your SWR's are good. Metal roof of the truck is the ground plane.
Edit- Yes, be happy with the results. -
Provided you calibrated the SWR meter (if it has a calibration adjust) then yes the SWR's look good. But the "8" I am presuming is your dead key reading? Seems a bit high IMO unless the radio has been modified.
The Lil Wil is definitely a step up from the China Mart antennas, though I will say the Wilson 1000 would make you happier.

I use a K30 by K40 mag mount on top of my Maxima. It it similar to the lil wil. Got 1.1 SWR Took about 3-4 inches off the whip. Very happy with the results. You should be, too.

The Galaxy has automatic SWR calibration.
It is a new radio, never been modified, refurbished or returned. I wrote Galaxy tech dept about the 8 watts, but haven't gotten a reply yet. Is dead key where you just press the key without any sound input? That is what I was doing.

The cb shop brought out a Wilson something that looked huge, seemed out of place on top of my pickup. I think what I got is plenty good. After the excersize in futility I had with the Wally World antenna, with this Wilson it dosen't get any better imo.Last edited: Nov 8, 2012

I was just snooping around in another forum, not a member, and someone with a DX929 is getting 8 watts like what I see in my DX939. In one reply someone said using a radio meter is no good, have to use a real meter for output measurements. I think I'm ok.

First off there is no such thing as an automatic SWR calibration. If anything your radio has a built in high SWR alert, as found under the channel LED. All it does is alert you if the SWR reaches a certain height. Even the owners manual talks of you manually setting the SWR on page 5....although it also tells you to tap the antenna while holding down the press-to-talk switch....which can give you an RF burn, so be advised, I'd unkey when touching the antenna and if possible, turn off the radio.
Yes the deadkey is where you push the press-to-talk button and do not speak into the mic, and you also make sure the vehicle is quiet inside, as the mic can pick up noise and transmit it, causing the deadkey to increase.
To each his own, but just saying unless you only care to talk 3-4 miles....how tall is too tall for you? My Wilson 1000 only has a whip height of 67 inches at the tip. Not that tall IMO. Heck right now I run a 9 ft antenna on my truck. You might think it's too tall, but ###### if I can't talk and hear 13 miles on 4 watts of power. -
The "real meter" is an external meter.
-
The way I understood it is that it's auto CALIBRATION, not SWR settings. I know there is no way around getting outside and manually adjusting the antenna. And yes it has a high SWR alert led too.
Even though I'm showing 8 watts, I suspect now that it is in fact in compliance with FCC regulations at only 4.
I'm a local delivery boy of rock/sand/dirt here in LA & general area. We use a cb when we see each other, otherwise it's nextel or my verizon when I need info now. CB is indispensible when communicating in the mines, but that's with my company supplied Cobra 29 in the transfer. -
You can't ever go by the meter on a radio. So many of them are off out of the box. best bet is check you swr with an external meter and go from there. Most antennas are ajustable and a good rule of thumb. If you check your swr on channel 1 and 40. If for example its a 1.5 on 1 and 2 on 40. Your antenna needs to be shorter. If its 2 on 1 and 1.5 on 40 antenna needs to be longer. The goal is to have low swr threw the whole Cb band.
