It would be helpful to know a little more about how these are all connected as well as some information about the single channel filters.
And the lengths of coax being used before you get to the preamp.
And a signal report from https://www.rabbitears.info/searchmap.php |
Sure. Signal report:

This is the filter that I use:

The filter is needed (on the East pointing antenna) as it picks up enough Ch 23 signal from the back/side of the antenna to interfere with the antenna pointing north (but NOT enough for a usable signal).
As far as lengths go, the VHF antenna (RG11) is probably around 50-60ft in length before it gets to the preamp. The North & East Antennas are about 6-7ft of RG-6 before encountering the first coupler (a small two-way splitter). The second coupler mixes the UHF Yagi (about 25ft of coax) and the first splitter. The connection between the two couplers and the preamp is done with male/male rigid F connectors, so there is no wire used for any of these connections.
The joiners, filter and pre-amp are away from the elements, so weatherproofing is not an issue with any change in pre-amp.
ALL the inbound connections also go through a ground-block BEFORE entering the amp/filter/joiner. The ground block connection probably adds a small amount of attenuation, but I'm willing to put up with this for the added safety.
After the preamp, It gets split (another 2way splitter) to the TV and to my computer for use with a USB Tuner. All these wires are RG-6. Wire length from preamp/splitter to TV is about 30ft. To the Computer is about 10ft.
With the VHF antenna located where it is, and the quality of cable. the signal is fairly reliable. It's the UHF frequencies that are problematic.
