Not worth it  Time owned: 0 to 3 months
even with the price being less than $7 this was a wate of money. I had hoped to used this antenna as a toss in the go box antenna. Not going to happen. Antenna looks ok but once you connect it to an antenna analyzer you find out the real story.

SWR on VHF was never below 2.0 to 1 anywhere.
On UHF is was almost dead flat at 470mhz but in the ham band it was 2.5 or higher.

I used a Comet CAA-500 analyzer and a good solid metal area to attach to away from other things.

So as far as I am concerned this antenna is a scanner antenna and no more. It will live in the junkbox until i get tired of looking at it and pitch it in the trash.

Anyone want a brand new one in the package?? $10 shipped!! LOLOL!!

GMRS only. 5/8th wave 39cm  Time owned: 0 to 3 months
Great for GMRS auto, motorcycle use
but it has physical noise, it sings when mobile.

By checking the wavelength division chart for example you will see only one match.
5/8th wave for GMRS, so you do get gain instead of loss.
It is ok for NOAA and FM.
Do not TX on VHF for it will overheat your radio.

Cons:
unusable on VHF HAM.
it sings from wind noise, two coil/trap whistles
picks up harmonics on VHF Marine channels.
not for VHF use.
Needs to be labeled GMRS only

It is what it is, low cost mobile antenna.
I suspect it is a sister to the UT-105 but with different trap frequencies.
