The UVSJ has a very specific function and is used when you want to combine UHF signals from one antenna with VHF signals from another antenna.

A UHF antenna will receive some VHF signal. The UVSJ filters out the VHF component from the UHF antenna.

Since you have signals being received on two antennas, the signals may arrive at each antenna at a slightly different time. When combined together they may offset each other and lessen the total amount of signal making it weaker. Using the UVSJ, when it combines the signals from the two antennas, there are no competing signals that will mix with each other and cause signal degradation.
Yes that's true if u use an amp like a channel master 7778or the 7777 amp
The feed line frum the ANTENNA to the amp if 52 inches long will increase the vh F RECIVE. ??
