RE: Range check question
Now then now then !.....
What you have to do is temper that information with what the power output is on your system. Here in the UK , we run lower power out than you guys across on the US ( 100mW ).
I transmit with antenna collapsed for a substantial time when bench testing JR Transmitters
We do a range test with Antenna collapsed ( ALL the way down ) and IF I DONT get at least 70 paces ( btw I am 6ft tall ) the as far as I am concerned that transmitter does NOT go out of the door !
If the transmitter has been specced correctly , then the risk of damage is minimal with a collapsed antenna. Transmit current is tuned for a minimum with min antenna.
