You know, I'll bet that if you had wound that 'bar' stock 'flat' instead of 'on edge', you could have knocked another couple of inches off of the antenna's height.
Something else to think about is that by making the coil's shape more efficient, you are raising it's 'Q'. Wanna be sort of careful about that, the higher the 'Q' the less 'bandwidth' that antenna will have. The higher the 'Q' the higher the efficiency, but the narrower the usable 2:1 SWR bandwidth. Sounds like you can 'improve' an antenna too much, doesn't it? Or does it just mean that a really 'wide banded' antenna is less efficient? Hmm...

[QUOTE="W5LZ, post: 243796, member: 129"] You know, I'll bet that if you had wound that 'bar' stock 'flat' instead of 'on edge', you could have knocked another couple of inches off of the antenna's height. Something else to think about is that by making the coil's shape more efficient, you are raising it's 'Q'. Wanna be sort of careful about that, the higher the 'Q' the less 'bandwidth' that antenna will have. The higher the 'Q' the higher the efficiency, but the narrower the usable 2:1 SWR bandwidth. Sounds like you can 'improve' an antenna too much, doesn't it? Or does it just mean that a really 'wide banded' antenna is less efficient? Hmm... :) - 'Doc [/QUOTE]
