Hi guys; i want to try this project to improve antenna signal strength,i have an outdoor antenna pic 2 Attach. my question to the acknowledged people here is! will i benefice if i add to more sets of elements like in the pic #1; thanks

 

If done properly, then "yes". If NOT done properly, then "no". In fact, if not done properly, you will actually LOSE signal strength. Adding elements quickly suffers from greatly diminishing returns. Your best bang-for-the-buck would be to add an amplifier at the antenna. I use an Antennas Direct model PA-18 amp at the antenna and reliably pull in UHF channels 65 miles away. Just be sure that you are AC coupled into the amp.

 

I also use an antenna amplifier which attaches right to the antenna terminals for the best available signal from the antenna it is attached to. It has voltage gain, drives several cables in my house, and removes problems rather than becoming one of the problems, for a rather low price.

 

Thanks guys; i also use a 15DB amp with power inserter,one thing i do not use is a 300ohm to 75ohms Balun transformer at the antenna, i connected the coaxial cable strait to the antenna.
these are the channels available in my area,see link; i get most of the 65 miles,maybe with a better set up or other antenna i would get more with better Q.

Hello,

Does the antenna have a folded dipole or an open dipole?
For a folded dipole, you will need the 300 to 75 Ohms balun.
For an open dipole you can connect the 75 Ohms cable directly.

When you want to look for an other antenna, have a look at the logarithmic periodic antenna:

It looks like a CM-2020 antenna. It has a 300 ohm impedance and they included a balun for the customer to use. Without it, they cut their reception power in half.

http://copradar.com/dtv/index.html has some helpful hints.

When pointing his antenna, I'd probably point it towards CH 36. It's a nearby channel that transmits a low power (15 kW).
