I've found 2 tends to have a bit less maximum range than all others, and 7 tends have the best range on VHF*...Both covered my whole house and grounds, and then some with no signal strength issues.
*It may be my antenna's...I followed Shango66's youtube video on making antennas, but I lack the IIRC VSWR meter he has so all I can do is grind the math, and cut off the same percentage of length as he did...IIRC from my college antennas elective if you want to change the effective impedance of a dipole at a frequency you can do it as a percentage of length, and it will hold for dipoles of other freqs as long as the impedance change is the same and the percentage is the same....At any rate my work is in the right ballpark to function decently, and that is what matters to me.
I've not set up a UHF BT rig, but have been wanting to get to that for a while now...
