The HF beams won't "see" the VHF antenna, but you want enough separation so
that the bigger antennas don't cause reflections that distort the VHF pattern.
Three feet is about a half-wave on 2M, and is the minimum you should accept
(air space between antennas, not center-to-center). I'd rather see five or six
feet of separation, especially if you have a tough path to the cluster node.

Subject: [antennaware] 2 Beams-VHF/HF-same mast?
What should I watch out for when putting a VHF beam for packetcluster
on the same mast as an HF beam for DX? What would be adequate spacing
between the two?
