As an official Cable/Satellite boycotter, I have elected to spend money elsewhere and get my digital TV via antenna.
My issue was that the upper spectrum (ch 8 & up) of VHF requires rabbit ears spread wide and long, while the lower spectrum (ch. 2-7) requires the rabbit ears set short and parallel.
I've spent some frustrating time fiddling and moving, scanning & rescanning but could never get both upper and lower VHF to come in with one configuration.
Then it hit me: compound antennae! I took a second pair of rabbit ears, set them for lower and attached them to the other set that are set for the higher spectrum. Success! I went from 12 to 20 channels!
By not connecting the UHF wire from the second antenna, my UHF remained undisturbed.
LOL, if only I watched more TV.

But, this is an under $10 help that might serve others, hence, I post.
