Hey all just curious if there is anything inherantly better about the receiver in a desktop or mobile scanner vs a handheld. Example, a Uniden BCD325P2 plugged into wall power in the house and connected to the same external antenna as a BCD996P2. Will one be more “sensitive” than the other? Thanks. Same question would apply for say a Whistler TRX-1 vs TRX-2 for example. Thanks!

See threads below, differing opinions. Not all RF environments are created equal. Personally my 536HP outperforms my 436HP a bit when external antenna swapped between units. Not a night and day difference, maybe a bar or two in favor of the 536 on the weaker stations

My gut instinct is handhelds tend to provide higher front-end gain which could more easily overload when using an external antenna. Uniden scanners perform better overall with an external antenna over GRE/Whistler scanners. The GRE/Whistler line of scanners, including the TRX-1 and TRX-2, suffer from many different RF overload related issues especially when using an external antenna. Anyway, the above threads should be good reading.

It's the old story of sensitivity vs selectivity. For those who want a receiver that can "hear better", we're willing to put up with some selectivity issues. If you turn down the signal strength, you'll more likely to only get the desired signal, that is if it is strong enough. One size does not fit all. Are you in an urban area (lots of strong signals around) or rural? Are you using a hand-held antenna or something more grand? Are you mobile or at a fixed location? Do you need to receive from all directions? YMMV.
