Antenna selection

I live between Tampa and Orlando. I made a home made antenna and get most of the channels from both cities, some not as well as others. I just put up a 40' tower for my cell antenna and decided to upgrade the TV antenna since I have the tower anyway.

TV Fool


There is no rotor

I have two TVs now might go to 3

All the cables run up to a common spot in the attic and there is a Zinwell Wide Band 6 x 8 Multi Sw #WB68 up there from the PO.


I was thinking of putting two antennas up there one facing Orlando and one facing Tampa?

And as far as amps, preamps, and splitters... I'm lost.

Thanks

If you are open to the idea of home built antennas my first suggestion would be a well designed, and built 4 bay with no reflector. Using the proven dimensions of the Mclapp 4bay, or Kosmic Superquad. Do not use the dimensions in the well known defective Utube board and coat hanger design.

UHF Kosmic SuperQuad (9.75x9.5) NO Refl.
mclapp's M4 (9.5x9.0) 4-Bay - NO Refl.
DIY TV Antennas 4 bays, 2 bays, Kits and more
Another proven well know design is the Gray Hoverman with NARODs for VHF. Dimensions were recently posted in a thread on this forum. Post #10 http://www.dtvusaforum.com/dtv-hdtv...0-help-me-witht-my-diy-hooverman-signals.html
The problem being that no manufacture builds a a simple bi-directional high VHF/UHF antenna that I could recommend for the few television markets were such an antenna would be ideal. I live in an area where such an antenna would be ideal. In another recent thread were this subject was discussed MrPogi made a good suggestion in post #5.

Keep in mind combining like antennas pointed different directions is seldom recommended as you are cutting the gain in each direction in half from what a single antenna would do, and also opening the door to more multi-path problems. But there are locations where such an arrangement could work quite well.
Start with one coax to one TV using simple barrel connectors where needed. Work out splitting and signal distribution after you have established good reception on one TV. The Zinwell Multi-SW should be replace with appropriate splitters for OTA use. When you add a single splitter you cut the signal in half, there can still be plenty of signal to go around. Avoid unnecessary splits and long coax runs when possible.

Wow, this is a really well structured analysis on the antenna selection! Congrats, I have found info of great value here as well. Keep up the great work, guys!
