EZ-Wire antenna
I have both the 16M and the 32M
version of this antenna.
It is a voltage fed end fed antenna using a high quality 9:1 "unun"
to provide a reasonably broad band match across the HF spectrum. It tunes
easily with any internal tuner. Because it is fed at the high
impedance/voltage point of voltage/current distribution on the wire there are
less ground currents that flow (at the feed point) and therefore the
radial/counterpoise/ground requirement is much less. In most cases the
radio's ground will do. A good common mode choke is recommended. I spoke
with CT1FFU and he said the wire lengths were arrived at after much testing and
that these lengths present the most consistent impedances in the HF bands with
the 9:1 windings he uses.
Don't believe the End
Fed antenna works without a "counterpoise"? Check the E-Ham
reviews of the Par End Fedz antennas. I have several of these too, they
work amazingly well.
I have the 32M
version of the EZ-Wire installed as an inverted "L" at about 60 feet
in my small yard with 1 tree. I attached tuned radials and counterpoises
just to check, they made no difference at all.
I also had a 133'
"New Carolina Windom" installed at 36' at the same time as the newly
installed 32M EZ-Wire so I was able to do some direct comparisons:
On 20M- 6M the EZ-Wire is better 90% of
the time, some times as much as 3-5 S-units stronger.
On 30M the EZ-Wire is better 75% of the
time, again with as much as 3-5 S-units.
On 40M the EZ-Wire is better 60% of the
time, often by a few S-units.
On 80M the Windom begans to win out more
often, but not by much, and not enough to disappoint me.
On 160M the Windom is usually stronger
on RX but the Windom will not load on 160M, the EZ-Wire will easily load on
160M and has given my some of my first 160M contacts so it wins for me there.
