Captured a quick SWR plot (0.5 per scale) on the Maldol EX-107 dual-band UHF whip on the Diamond HRKS stick-on external mount. Didn’t try any tuning - just initial performance on the back window of the car. Looks OK for 144/440 bands. Not good on 220 (as expected). Too tall for daily use without removal/reinstallation each trip.

Second whip tested is the Comet B-10 on the Diamond HRKS stick-on mount. Antenna is only about 12” length and comfortably clears the overhead garage door. Being much shorter, it has less Q and a little higher VSWR than the longer Maldol whip. Will be field testing this antenna on 146, 220, and 450 bands with the trio-band mobile.
