    Well a while back I asked about antennas on a KW T800. That's no longer my worry, as I found out I will not be getting one of the new KWs. Instead I'll get an '07 Pete 386. At least I think that's the plan, who knows at this point.

    Anyway, this past Monday, I discovered someone felt they could use my Wilson 2k antenna more than I. This is one of those things I never thought about looking at during my PTI. It wasn't until after loading, and talking a couple of times, I noticed the radio wasn't sounding right. No squelch, and then I leaned down in the seat to see that my antenna was gone. This has to be another one of our drivers. As my truck is parked at the "yard" with the other trucks. There are several other drivers that use expensive antennas, and their antennas were not messed with. Plus just a week earlier I had the License Plate ripped off the truck.

    Well since I had to get another load, I had to replace the antenna. I have 2 old "junk" antennas, and chose to put one on. However I refused to use my Galaxy 459, with the RFX 75 with an antenna that has not had the SWRs set. At this time I was real concerned that I had damaged my radio anyway. Even though it is required by the company to have a CB, they will not provide one, OR an antenna. So instead I had to purchase another cheap radio. I put it in, and have been using it all week, without setting the SWR, which I know has to be high.

    With all that said, I want to use my Galaxy, with a good antenna, like the Wilson 2k. I've never used a "quick connect" for antennas. Once I get the SWR set, would using a quick connect alter the SWR anytime the antenna is removed? I'm thinking at least I could remove the antenna, put it inside the truck while it is parked. Then wait to see what the a-hole messes with next.

    You will have to readjust the antenna because the quick disconnect adds length to it.

    Ok, I understand that the quick disconnect will add length and the SWR will need to be set accordingly. What I'm asking is will the SWRs need to be reset every time I remove and replace the antenna?

    no, you won't have to reset it each and every time.
     
    Eaton18 Thanks this.

    I am still trying to figure out the "18 feet" of coax rule.

    I have put up antenna with 10 feet, 25 feet and 600 feet of coax. The feed loss was there, but the SWR didn't change significantly.

    Now using ladder line, THAT made a world of difference on SWR.

    Coax don't care how long it is and 18 foot is a wrong length anyway ....Ladder line ? well for a G5RV have at it otherwise unless you have a tuner it is useless.

    because if you use a ladder line on a long wire antenna, you have to include that in the design of the antenna. As I understand it, what length will give you a 50ohm impedance.

    Where as if you use coax, you can go off a 1:1 balun at the feed point for most designs.

    So WHY do you have to worry about MUST having 18 feet of coax in a truck?

    Read this board enough, that comment of needing 18' of coax comes up enough.
