If a Imax was mounted in a tree, just enuff to get the feedpoint to 36 feet, with not much of the ant. above the tree, how would the tree itself effect the ant's. signal? I'm wishing to kinda stay in stealth mode.

it will work ok until things get wet,
when the tree is wet, or even really moist on the inside, it will affect the SWR of the antenna.
i think you might be wise to look at some of the wire antenna designs that you could put up in the back yard.
check out the "half-square" antenna.
i made one of these and it worked pretty good.
bi-directional, and not great for local comms. but did good for DX, and gives a good SWR without a tuner.

KV is right. The tree's moisture content and any moisture on the branches and leaves will affect it. However, if you can mount the antenna some distance from the tree (like side mounting on a tower) then it will have much less affect.
Wire antennas are the most stealth antennas known to man. Like KV, I highly suggest a wire dipole or some simple antenna to begin with. I have wire antennas at my home, and you cannot see a thing. My home is on top of a hill in a very exclusive area, and the neighbors (although not very close) are very sensitive to asthetics. Even though there are no CC&R's to deal with, I still have to live there, so I chose wire antennas to keep the peace. |
