A Electron Recommendation for Tv Reception.
Question 2.
As with the recommended preamp , all most all preamps are designed as 2 parts. The outside part that is the actual signal preamp and is mounted close to the antenna , and the inside part that is the power supply/power injector part.
The power is fed to the outside part through the coax.
For one Tv connected no splitter is used.
For more then one Tv connected I recommend Holland Electronics splitters.

For 2 Tv's connected use a HFS-2D , 2 way splitter.
For 3 Tv,s connected use a HFS-3D , 3 way splitter.
For 4 Tv's connected use a HFS-4D , 4way splitter.
Question 1.
Going to 40 feet antenna height will improve the reliability of weak station like W47DL-D UHF channel 47 and get a few more Tv stations that have less signal strength.
Here are some ways to go higher with the antenna.
