Greetings,

 Which antenna would be a top performer for a 10 mtr transmitter with 50 watts out?  I would prefer a perm. vs. mag/mount.  I do have a older 10/11mtr. M/M from Rat shack trimmed to 28.400 but as for a permanant mounted ant. what works well ??

I use a Larsen NMO27BCO coil with a stainless steel whip mounted on a permanent NMO mount.  It's short enough to sit on the roof of my Tahoe without banging anything except the lowest of branches.

Mag mounts because of poor capacitive coupling at frequencies below 30mhz should be avoided.
The best performance will occur with a 3/4 inch hole mount NMO in the cener of the roof.
A base loaded 1/4 wave design like the Larsen NMO27C will be fine.
If you intend to trunk mount an antenna, a top loaded
type antenna would be a better choice.

Stainless steel "CB" whip cut to 98" length, installed in a ball mount high on the fender of the vehicle.

Very strong, secure, weatherproof, good ground, efficient antenna -- impossible to beat with anything other than the same whip mounted in the center of the roof, also using a ball mount.  (I've seen that done, and it's the best performance you can get -- but kind of ugly and crashes into stuff a lot.)

I know the arguments about using mag mount antennas. i am running a Wilson 500 mag mount(with short wire running from mag mounting bolt to ground) on my work van while I wait for my screwdriver. Running a Ranger 2950 I had a good qso with Costa Rica from SE Texas. Lately I have had no problems making contacts. Now running a FT-450 still making good contacts.

I have used a RS HTX-100 and SS cb whip cut for 28.400 bolted to the bed of my pickup truck.

I use a Hustler ssm-1 ball, mount, spring and a ss 9' whip mounted atop a taurus wagon roof and centered. It is longer(108"+spring) than a 10m quarter wave whip (98") but I use an LDG auto tuner to work the warc bands up to 20m. and need the extra length, in fact when I operate from a hilltop and am stationary mobile for a long time I have used an electricians split bolt to clamp another 48" whip extension near the top. apx.(12'4") this simple technique works out well.

I used a  venerable K40 magmount right in the center of the roof. Seem to work well. Worked Alasksa from Kansas on 4 watts with my 148GTL.  Of course when 10m is open, its open..
