If your antenna is 10 years old, install a new Sensar IV head for less than $75. It is much better than the old Sensars. And only two pins to remove and replace to change! When I changed, we could see a very significant increase in the available channels, and the signal on all the others. As we are now in a very weak signal area, I bought and installed a new Sensar Signal meter with an addition booster internal. Signal strength almost doubled. Watch channels from 65+ miles away, as we already know that weather affrects signal here, we are waiting to see what the overall effect is going to be.
