Then I guess it has nothing to do with the Ohm-Igod ratio.

However things like reflection, refraction, absorption, diffraction, and scattering create what is called multipath signals. These signals create havoc among the good signals you want to receive. Sometimes the signal gets to your antenna at a perfectly delayed time 180 degrees out of sync and cancels the original signal (bad thing). Other times the multipath signal arrives at a good time and actually boosts the signal (good thing). If you have ever experienced the "ghost" image back when CRT tv's were popular that was multipath waves being displayed on the tv. (usually down and to the right of the good image). Back to the topic...the waves need to reach your antenna above a threshold that is predetermined in order to actually receive the signal. So to recap...if the waves are arriving to your antenna with too much jumble or without the proper amount of power you will experience a bad signal or no signal at all. Because the waves are extremely small there are times that moving your antenna slightly will produce a better picture because you have changed the angle for the way the multipath signals are being received.

That all sounds good But I would rather have a fuzzy analog picture than an HD picture that keeps going off and on in the middle of a program.

With HD digital channels, you will either get a great signal or nothing. The power booster for the antenna should be on. Follow instructions for auto channel for you TV's. Point antenna to 4 points of compass and run auto channel. Make a note of best reception after running. Analog channels will show even if the signal is weak, whereas a digital channel will only show if it is strong. The batwing antenna has a UHF side piece that snaps onto the batwing antenna at a right angle to give better UHF signals (Channel 14 - 999) depending on the area you are presently in. Another good antenna is the Jack. I have had both and the Jack worked better, but in all fairness, I could not install the UHF attachment to my Batwing as I had a vent cover that would not allow the batwing with the attachment to lie flat on the roof. If you really want great TV, get a satellite dish, and control box for your trailer. Hope this helps
