SWR help

Hey guys, I recently got an SWR meter from a HAM shop in town and the instructions are horrible. Can anyone describe to me how I can use this thing to figure out my SWr reading? It is a Lodestar SWR-3P SWR/WATT METER. i know how to hook it up but everytime I try to get a reading the meter just shoots up as far as it will go. everytime. My setting options are 10W/FWD, REF/100W, SWR, POWER, and SET & FS ADJ. Any help will be appreciated...

Unless your antenna is grounded (which makes SWR impossible to set at all) you should be able to see the hookup here:

http://www.firestik.com/Tech_Docs/Setting_SWR.htm

The antenna mount should be grounded, not the antenna. Most times SWR is pegged the antenna isn't assembled properly, the nylon washer is out of place or the antenna is touching ground somewhere...

edit: found what I was lookin' for at Stu's Off Road:

Nice diagram of antenna installation.

Try this:
Set to "10/FWD"
Set to "power"
Key radio and adjust "set" knob so the needle is on "set"

Change "power" to "swr" and key radio. This should give you an swr meeting.

If you don't have this resolved by Sunday, I will be through Auburn in the early evening and can give you a hand.

I realize this post is a little dated but since I needed the instructions for the same model I thought I would post an update.

Here is a link to the manual

SWR-3P Manual

(like referenced above) Here is a link for help tuning your antenna

Tuning help...


The best I could get was 2.0 on 1, 1.5 on 19 and 2.0 on 40 so I guess I am right on the cusp so it looks like I need to check my bracket ground... Anyone have trouble getting a good ground plane with the unibody on a WJ?

Those are normal SWR readings and are perfectly usable. The SWR readings can depend on the quality of the antenna. Some of the cheaper antennas just don't have the bandwidth for a better SWR. The location of your antenna installation will also have an effect your SWR.

...that is good news, everything I read said if I was under 2.0 I was in good shape but it if was over 2.0 I need to check my ground plane so since I was right on 2.0 I was concerned.

Thanks again, this is my first Jeep, CB, and overall 4x4 experience. I am glad I gave it a try, I feel like I am going to be a "lifer" as I am loving sport.
