Kenwood: Kenwood TM-281 and PulseLarsen glass mount, motorhome, your thoughts?

Interesting, thank you. A google search of KG144UPDL - Google Search turned up literally no results, and try as I might I couldn’t seem to get the guesses on dashes right.

No problem. It helps that I'm familiar enough with how such product IDs are usually structured.

It's the Kul-Glass glass mount VHF antenna.

I used a UHF model on my wife's car a long time ago. They work well enough.

All considered, I can see no benefit to making a 3/4” hole in the roof to use an NMO permanent mount.

Because a "Ground plane" is so overrated...

After looking at the pictures there's just one thing I think I'd recommend. That's a '
'bumper' strip on the roof/wall lip beside the antenna(s). That's not necessarily a "run right out there and do it!" thingy, but soon, sort of.
There are 'problems' with any glass mount antenna. They deal with the mount 'size' and ability to do that 'coupling' at various frequencies, two meters not being a biggy.
I'm not sure, but if the top isn't metal, mounting the antenna lower isn't going to make a big (if any) difference. If not mounted to metal then you will have to provide the "other half" of the antenna (groundplane, counterpoise, whatever you want to call it). That's just another problem of a different nature, oh well...
