External antenna for my Uniden GMRS480 (SMA Male) ?

I guess I lucked out when I bought refurbed GMRS480 radios in 2002 as a backup since it accepts external antenna, something no longer available it seems on GMRS radios.

Anyway I’m looking for an antenna for them, longer stubby antenna and possibly car antenna with a magnetic base, they use an SMA-Male connector I believe, see below :

And have a little “notch”

Anyone know what antenna(s) would fit the bill ? Thanks !

Found this on eBay :

  • Connector: SMA-Male type connector
    • Band: Dual Band VHF/UHF
    • Frequency: Dual Band 144MHz/430MHz
    • Gain: 2.15/3.0dB
    • Max Power: 10 Watts
    • V.S.W.R: Less than 1.5
    • Impedance: 50 ohm
    • Style: Flexible whip
    • Mounting: Magnetic Base
    • Antenna Length: 48cm
    • Cable Lenth: 3m"

Looks good except that it “tops out” at 430Mhz vs the 462.x Mhz of GMRS, would it still be of any help ?

Thanks !
