So I thought I would wrap this up. Using my Kenwood TM D710, some more testing shows the flexi whip to work very well on 2m and okay on 70cm. On 70 cm I can hit the nearby low azimuth repeater full...

Ha, I knew it. Good for you to have the educational background compatible with one's hobby. Must be nice to be able to get into a radio like that and fix it. I will keep those pics handy should...

I don't care for their gasket. Today I seated the gasket carefully against the roof and tightened the antenna. I could still get a piece of paper between the gasket and antenna base along most of...

So this is what I found. Apparently the gasket had caught a bit on the NMO mount, so I removed the gasket and reseated the antenna without it. I don't have a SWR meter for my TM D710 so I took my...

I am off by 0.5 inches, too short. I understand the cut chart is for a "typical" installation such as a roof mount NMO. I understand adding the SO259/PL259 connectors will change things but I...

Can't believe I just cut it too short, 1/2 inch too short.

Had the 1/8" over the 19.5 stuck in my head and cut it to 19 1/8", which is about 149Mhz :mad::mad:

This is why it must be so nice to have an antenna analyzer.



That is exactly why I have the center roof mount! Those are some good references, one I had not seen before.

okay, will do. I ordered the antenna today from Tessco. The real world performance differences are likely due to all the little differences in theory assumptions vs. actual conditions.

Dave, If you have an MFJ-269 you should be able to check the SWR across the 70 cm band on the 2m 1/4 wave Flexi-whip. Would that be too much trouble?

That is correct, about a 3 foot pig tail would take me to a Yakima roof bar that will only be on when I have the RTT. I agree it would be sub-optimal, just how much.
