The frequency is good, but here is the difference between the PG and the EV Re2 we've been discussing:
Channels -
PG - 9
EV - 1112
Bandwidth
PG -unknown
EV - 28 Mhz
Antennas
PG - Internal. You get what you get.
EV - Dual external 1/4 wave dipole, detachable w/ TNC connectors. Other options available.
Transmission Power
PG - 10mW
EV - 30mW
Battery Indicator on Receiver
PG - No
EV - Yes
There are lots more benchmarks, grouping, etc... but they really aren't in the same league. It's just a price and performance thing.
In my opinion... the price is so close, it's foolish not to step up since the EV is basically in your given range. BUT, the Shure is the best system for IT'S price. Either way, I'm proud to sell both brands and proud to have great pricing on both.
