WOW ! So many un-similar antennas within one array. Sounds like your set-up could create much 'multipath'.
Not really, I have two mount, a 40 feet tower with a pole of 10 fee on the top, the Archer was installed there by the previous owner of the house. Two others are on the frame of tower at different locations. The FM antenna is near the roof. Plus there is one scanner antennas on a cross beam at about 40 feet and one scanner antenna top of the 10 feet pole.
And two on the other side on a chimney mount.
with so many antennas in your array, you likely have a significant line loss factor as well as great potential for multipath or signal reflection problems.
I don't think so, I have different coax coming in different tuners. I have 4 tuners, Sanyo LCD, Samsung Plasma, Sony HD radio and Zenith CECB, all with their coax coming from their premap. If you look at my TVFOOL results, WVNY-DT is broadcasting not even 500 watts at my location, -7,9 dB NM and I get it 80 % of time. Why ? One of the reason is my 4228 is blocking a strong co-channel station in the opposite direction of WVNY and since I placed my 10y13s bellow it, I get it now with the SRC form Trois-Rivières blocked by the 4228 a bit.
Some users that have better TV Fool results them myself and get WVNY worst then me with the same Antenna and preamp.
I've been testing my setup since 18 months and I have previous experience with other type of antennas (CB, HAM, Scanner and Shortwave) plus I have 20 years experience as a Electronics Technologist, so I am not a Beginner.
I am having fun making all of this work and it's a bit of luck also. But I could run into MultiPath problems also becasue of this new 4221HD, you never know and I will see.
I think all your missing now is a Parabola
I would love to get a CM4251, there is one in Pike River Quebec, but my neighbors would really freak out.
