[Antennas] Elevated Cushcraft R-7?

[Deon Erwin ZS1ZL]

Bob

I began my post by saying that I do not know the R-7, but can attest to the
dramatic performance increase when the AV-14AVQ was elevated, by comparison.

I also referred to the effort to test the AV-14AVQ at ground level with
buried radials and then raise it with elevated radials.

I realise that the R-7 requires no radials.  My point is that it would be a
simple procedure to move the radial-less R-7 from a low level to a high
level to determine its best performance - there are no radials to dig up and
install in an elevated position.

All locations are different.  Test the R-7 at low and high elevations and
see where it performs the best.

The more comments I see regarding the R-7 and whether it should be mounted
high
or low, the more amazed I become.

Why are there so many comments that seemingly ignore the significant
difference
between ordinary verticals and the vertical half wave?

Specifically, why do so many comments explicitly discuss the finer points of
radials when radials are NOT a part of the R-7 configuration. It is a
vertical
half wave, and does not use radials.

Fire away!
