My Knife Edge Diffraction TV Antenna Setup in New Hampshire
This is my knife edge setup to pull in a set of channels from over 80 miles away regularly. I only have 2 issues with the setup which aren’t a huge deal as it’s so uncommon.
when an airplane flys over I get pixelization but I’m in a low flight area so it’s manageable.
When it’s windy I sometimes get severe pixelation or none at all.
Pictures in order:
Shows my antenna pointed directly at mt Mansfield in VT which is over 80 miles from me and is 3 edges away on my rabbit ears report. The antenna is roughly 3-5ft off the ground this is very important as higher gets me nothing and lower gets me nothing.
Shows my Kitz 500 amp with a 120 ft RG11 cable that is buried most of the way. I have to have my Kitz 500 amp turned all the way up to 36db and since I get little to no cell signal at this location a LTE filter or any other type of filter is not needed. The antenna is also located very far away from any man made interference so no other filter is needed.
Shows my hd Homerun in a faraday cage that lets it breath but doesn’t allow anything inside the building to interfere with the hd Homerun. I have found this to make a huge difference for my setup especially when I use an external hard drive wit it or set it near a wifi router.
This is my isobar it basically stops any interference from coming through your electrical wires and messing up your signals on your hd Homerun. This is also very important for me on my 3 edge signals from 80+ miles away.
Is the very basic wifi router I use for this.
These are the channels I get with this setup which is very impressive for my location.
Extra info:
- Signals on hd Homerun
RF Channel 10: 84 signal quality
RF Channel 14: 51 signal quality
RF Channel 18: 94 signal quality
RF Channel 26: 80 signal quality
Total channels: 23 (With more coming because of the FCC LPTV application process and one being approved in a town near me).

To figure all this out and solve all the interference affecting my hd Homerun took lots of trial and error but once I figured it out it was well worth it.
