As a TeleComm Engineer I disagree with this. In that case you must use an antenna with a wider radiation pattern (reception angle if you will) that covers all transmitter sites with enough gain unless you only have one TV then you can use 1 antenna with 1 rotor.

This Frankensteinas I unfortunaelly see all over the place nowadays might work subjectively for the untrainned user depending on his/her needs but if you measure with the proper test equipment the perfromance of this setup you will see that it degrades the signal. No wonder all times big name manufacturers like Channel Master do not manufacture neither recommend this "monsters".

Just my 2 cents.
