Thought maybe I could get a clamp to clamp the larger mast around the antenna base and see if that would hold it without smashing the antenna.

I think what I'm going to have to do is mount it to the factory mast, then slide that mast down into a larger one and figure out out to secure the two together without damaging the coax by running a screw through it.

I guess I'll have to cut the mast all the way down then I could put the cable in and see how that goes, unless there's a better solution.

what kind of connector is on the lmr600, an n connector or pl259 connector is is aprox 3/4 inch in diameter which should fit the pigtail pipe on the antenna base. pix would be nice.

Hiding in a coffee shop.
On many commercial antennas, there is a short whip of cable coming out from the antenna that you'd connect directly to.

That takes the strain of heavy/large coax like Heliax off the connectors.

Just use a 1-2 foot long jumper of RG-8 or whatever you have handy.

It is an N connector. This picture is indoors, but you can see the big black part that is what will not fit.

I've actually got an antenna with one of those pigtails. I've got some Lmr 400 I could make a jumper I guess, but I just don't think I'm very good at putting those ends on.

I see there is no soldering when putting on N connectors. Think I'll make a jumper. wonder if I'll have much signal loss.

Just Curious, how did it turn out ?
What was the motivator for getting the 600 over the 400 ?

Hello, and thanks for your question. Well, I guess wanting to get the best signal I could. My antenna is about 100 feet from my radio . I have a cell tower across the street and power lines . If I moved my antenna to where my radio is, the power lines would be about 60 feet or so from the antenna. Which I wonder how much interference would come from the power lines. They are on telephone poles. The lmr 600 is too thick to go through the diamond antenna connecting tube, so I had to use an lmr 400 jumber to go through that. I had an austin ferret antenna connected to it. Which I found to do a good job especially on state police. Over the past 2 weeks I have switched to a diamond antenna, which does a good job. I've been tempted to move my antenna closer to the radio, but don't want to waste my time if there is going to be a lot of interference from the lines. So to answer your question, to get the best possible signal. Any thoughts on the power lines? I do pull in from 60 miles away, be it a little static. I can understand it.

As like you I got a little the same dilemma, best location VS signal lost in coax. I did consider the 600 also but the diameter put me off, especially for my coax routing, never considered the antenna mounting pipe issue.
