Doesn't the excellent manual make this CRYSTAL clear !! (well mine does anyway) It states that the aerial MUST be 1 metre long, no shorter, longer is NOT a problem, what could be clearer ? The Rx RF performance is, amongst other things, a function of antenna length not model type !

You can of course compare Rf values using the software, NavView, to read out the values.

Weatronics produces arguably the best and most comprehensive manual (available on their web site) in the model industry as well as top notch products !
