There's no particular benefit for using a full wave vertical antenna as far as I know. For vertical antennas, once you get to something like 5/8 wave length the radiation pattern really get's 'odd', breaks into numerous 'nodes'/'nulls', not much 'low angle' stuff. Matching impedances (SWR) also get's sort of difficult, the impedance of an end fed full wave antenna is nowhere near 50 ohms. Certainly not impossible to match, but not exactly easy/normal.
How about mounting the thing on the side of a tower? That's not impossible either, but it does have complications in that the radiation pattern will certainly be affected, changes in 'shape'. There tends to be a 'null' in the direction of the tower. If that suits your purposes then that's good. If not, then it's not so good. If the idea is to experiment, see what happens, knock your self out! If it's to gain some advantage, that's really 'iffy', just depends on what the disadvantage is you are trying to get rid of.

[QUOTE="W5LZ, post: 408666, member: 129"] There's no particular benefit for using a full wave vertical antenna as far as I know. For vertical antennas, once you get to something like 5/8 wave length the radiation pattern really get's 'odd', breaks into numerous 'nodes'/'nulls', not much 'low angle' stuff. Matching impedances (SWR) also get's sort of difficult, the impedance of an end fed full wave antenna is nowhere near 50 ohms. Certainly not impossible to match, but not exactly easy/normal. How about mounting the thing on the side of a tower? That's not impossible either, but it does have complications in that the radiation pattern will certainly be affected, changes in 'shape'. There tends to be a 'null' in the direction of the tower. If that suits your purposes then that's good. If not, then it's not so good.
