raising the height of the dipole above the ground
from 3.5 to 6.5 feet was one of the things i did to
fix this problem.

The other one no one has guessed yet...


S.
This sounds like 20 questions. You are not telling us what you have. One
would not expect somebody to measure an antenna at a height of 3 feet. A
dipole would have an impedance of around 75 Ohms, which would give an SWR
into 50 Ohms of around 1.5:1 Are you using 50 Ohm coax and a 50 Ohm
meter?


Yes, all 50 Ohms.


Is there a gamma match, or such, to adjust?

No. But hint: a physical parameter of the
dipole was adjusted.



Is it a dipole or a folded
dipole? Is there a balun? Did you buy the antenna or build it (I suspect
the
intent would be different)? Since you are using an SWR meter, are you
putting enough power into it to get out of the nonlinear range?


MFJ-259. Home-made dipole using aluminum tubing.

There are only so many physical parameters of a
dipole, folks! Just list them and you should hit it!


Slick

Having no adjustments, and presumably no 62 Ohm coax, you must have bent it
into a V to get 50 Ohms. If you put a parasitic element on it, it is not a
dipole.

I didn't have to do that. It's a straight regular dipole.

No parasitic either.

================================

Having no record of who said what, or what the discussion was about, someone
may be interested in little program INV_VEE which, amongst other things,
demonstrates how the feedpoint impedance of an inverted-V dipole varies with
the enclosed angle from 0 to 180 degrees for any height above ground.
