After seeing the different posts of ganging multiple antenna to achieve higher gain, it has got me thinking of making a string of bowtie antenna to go across the peak of the roof to achieve a ultra high gain antenna. What I am in need of is someone to take a few measurements for me. With the multi bowtie antennas like the Channel Master 4228, what is the length of the active elements (the bowtie). How far apart are the bowties spaced vertically and horizontally from each other, as well as how far from the reflector are they spaced. It should be easy to gang a large string of then across the peak of the roof to achieve a high gain array.
Currently I have a homemade antenna on a 20ft tower, with a 10ft mast above that. The antenna output is fed into a 300 to 75 ohn balum and then into a Channel Master 7775 pre amp. With this configuration I am getting some signals with great strength, but my problem is that directly in my line of sight I have some trees. (about 80ft to the south of me) To place the antenna line of sight over these trees would require a tower of 60 to 80ft. I have found that even a 2 foot increase in height changes the signal from 68 to 75. Another foot higher and again an increase in signal strength. The atmosphere plays a big roll in the reception of signals for me. Most of my stations are 60 to 80 miles away. The OTA reception is a hobby for me, as I use satellite and cable for my TV. Maybe in the future I will get a higher tower.
Here are a couple of pictures of my project antenna.
