Bigger is better ?

Has any one purchased something like this and unscrewed the antenna from the magnet and see if it fits SMA or an adapter?

It's a MOBILE antenna. The only antenna coaxial connector style used is on the end of the cable. The antenna itself screws onto the base using something like a 1/4-20 or 3/16-24 thread. It is not meant for and never was meant to be mounted directly on top of an HT.

I'm curious this might sound a little weird...
I was thinking about using JB weld to roll my own thread adapters than wrapping the metal to metal with special foil i have ...?

I think what the Captain was saying, is that this 19" antenna isn't any different than a HT 19" antenna - except that it was built for mobile use only. It isn't bigger nor better; just built for a different application. It would be a waste of time and money to convert it for HT use considering that you could just get a Comet HT antenna for $25. Probably just ruin it if you took it apart . . . it is what it is . . .

Alright. thanks. i found this http://www.arrl.org/files/file/Technology/tis/info/pdf/9803037.pdf so ima get to reading be nice if there was a little bit more to read up

question, how well would a 20 awg wire antenna work? exam: 19.75" of stranded wire soldered to the Center pin of the bnc or sma connector? and yes the best way to make an ht work decent is some sort of magmount or other coax fed antenna.

A 1/4 wave is a 1/4 wave is a 1/4 wave and with no groundplane like on an HT they all suck. It does not matter if that 1/4 wave is 20 ga wire or 3/4 in pipe it is still a 1/4 wave without a groundplane. I told you before that if you want performance throw the HT away and get a mobile or a base radio and the antenna to go with it. You are wasting your time trying to gain something by playing with those antennas.If there was some magic combination the antenna manufacturers would have done it by now. The bottom line is it is still an HT and no matter what you put on it it will NEVER perform nearly as good as a decent mobile radio where you can mount a decent gain type antenna over a decent groundplane.

Sure, the worst that could happen is that the power supply is susceptible to RF and the voltage regulator goes nuts on key up and throws about 20 volts into your gear at which point in time SWR and antenna performance is the least of your worries.

That power supply is a paper weight cause I have one more im using, just using that is a artificial gtound
