TV fool and photo of current equipment attached, I'm very pleased with the Super G-1483 for UHF, and still beleive it out performs the 91 XG at my location 70+ miles from transmitters. My VHF antenna is a AC Y-10 7-13, and I have a little trouble with channel 8 at times, whereas 10, 12 from portland and 13 from Tacoma are trouble free. I have another Y10 and will stack them if I have too, but I'm reluctant to put that much additional weight and wind load on my mast. I have lowered the antennas and mast 2' since the photos were taken, so there is less mast above the idler than in the photo, this had no effect on UHF or VHF reception. Are there any other options for improved VHF at 70+ miles? I have looked at the winegaurd, but didn't think I would see a whole lot of difference either way. Thanks in advance for your advice.

The VHF is usually hampered by the low transmit power and is as weather dependent as the UHF. The UHF - you usually have to look for days with high pressure and clear sky's for decent reception.
60 miles either way is usually about the limit for reception.
VHF - when there is a lightning storm, you get drop outs from the lightning.
I would say that you would be at the limit of the strength of the tri pod mount at 3 antenna's. Really not much to gain by adding the 3rd antenna or 2nd antenna - if you only want to count the VHF + VHF.
Even way back in the 40's, the antenna installers guide recommended that you keep one antenna away from the other antenna by 1/4 wavelength - which might be at least 6 feet, depending on which channel you wish to receive, and use two identical length wires from the antenna to the pre amp.
I see what I think is a pre amp - several feet below the wires coming from the antenna's, but I don't know which model of pre amp you have or if it is even a pre amp at all.
Your attachment shows pictures, but nothing for a equipment list.

UHF Super G 1483 Hoverman. No issues here.
VHF Antennacraft Y-10 7-13.
Pre-amp CM 7777.
Rotor CM 9521 with thrust bearing.
RG-6 Coax.
Winegaurd distribution amp in attic.
No splitters in the house, everything RG-6 direct from the Distribution Amp to 4 TV's with built in digital tuners.
According to the engineer at antennacraft, 42" is the correct verticle spacing if I choose to stack the two Y10 7-13 antennas for VHF.
I would prefer to stick with 1 VHF antenna, but cannot find anything currently available that looks like it will gain me anything for Channel 8. The rest of the VHF channels have no issues, Thanks for the help.
