The accuracy is good, pretty fast acquisition as long as the antenna is oriented well following the reception level indications, the increase announced me seem very optimistic (5 m and 8 m in VHF UHF) but I 'did my tests primarily with wireless microphones VHF (170-235 MHz) and UHF (500-870 MHz) and given the very low transmission powers must be very close to get a stable measurement: 8-10 cms VHF and 15 to 20 cms in UHF. On my talky-talkies VHF and UHF much more powerful, acquisition due to the higher radiation was carried much further.
