Hiya, Matt --
Yes, your deduction that the guy tension bearing in on two faces (top and
front) is correct. This is also illustrated on the Rohn drawing C620643-R
and those are the two faces that they are refering to where they want the
rebar. There's probably nothing to be gained by having rebar below and
behind the anchor in the concrete. ALWAYS follow the manufacturer's
specifications as your construction minimum. If you want to over-engineer
and over-build it, follow accepted standards and practices. Sometimes tower
and antenna builders do things that have more psychological benefits since
they add little tangible improvement to the system. If it makes you feel
more comfortable, feel free to pursue it as long as you've followed the
manufacturer's specs up to that point.
73 and good luck, Steve K7LXC

The cap is needed to keep the Icom 8 volts off your mic cart. Icom uses
amplified microphones and the Heil is not amplified. There is 8 volts on
the mic audio center conductor for the Icom mic amps...
Heil says to increase the first audio state gain with the resistor
change. I still don't know which resistor it is!

The rig is great...even without the amplification it works fine, but to
get full compression for contesting, you need a little more
amplification.... Most hams don't even know they need more amplification
and are quite happy.
I use an outboard amp on 10 meters and it works great. The problem comes
in where I have RF in the shack due to SWR or being close to the antennas
on low bands...

Message-ID: <15820.9603151943@earl.encore.com>
Well, it took six weeks and intervention with the head of ICE to
get them made at the factory, but I got three model 309H surge
suppressors for balanced lines. I've figured out just how I'm going
to mount mine on ground rods below the antennas, with a coax
suppressor at the ground panel outside the shack serving as a
second line of defense. The other guy in the area who got one
of the three units will be mounting his right at his "Humongous!"
brand copper ground bar with his other suppressors. Just need to
get a test for transparent transmit operation on 160 meters done and
I'll be ready to sign off on these and get on with my life.
The bad news is that I was told that these three were the last model
309 suppressors that ICE will be making. They have no interest in this
product anymore. Perhaps this was an emotional statement and they'll
have a change of heart, but I'm not holding my breath.
So as I add antennas with balanced feeders I may have to reverse
enginner the ICE unit (and figuring out the type of toroid it has
inside is the only trick to that: maybe they'll take pity on
me and just tell me). Or else I could use the "spark plug" type
suppressors Wireman is said to sell, or trust myself to make them
and get the gap right :-)

I built two EWEs last fall. Both were constructed to the dimensions cited in
the first QST article for a compromise between 80 and 160 coverage. They were
erected well prior to the publication of the second QST article that described
the array of four EWEs. A few weeks later, I put up a short (~200')
terminated Beverage to the NE.
I thought that the receive pattern of the EWEs might be negatively impacted
from close proximity to each other. With that in mind, I tried to keep them
as far apart as practical. One was oriented NE and the other SW and were
sited with one facing the other, separated by about 15'. From the end of each
EWE, a shielded wire ran about 8' to a switching relay arrangement I
constructed to select which EWE would be fed to a ZJ Beverage Box. From the
ZJ box approximately 100' of RG-8X runs to an ICE splitter (includes a 2-4 dB
preamp) and then to a switching relay box to select whether the TS-940 listens
on the transmit antenna or receive only antenna.
During the first week of operation, the EWEs just didn't seem to hear very
well when compared to my transmit antennas (80: 1/4 sloper at 64'; 160: 1/4
sloper at 100'). Over the course of 3-4 nights of listening, the NE could
hear a little, but the SW was pretty deaf. I thought it was the EWE select
relay and/or the wire from the EWE to the relay box. I changed the wire from
the EWEs to the relay box and noticed no improvement. I then removed the
relay box and connected the ZJ Box directly to the NE EWE. This seemed to
make some difference. The NE EWE could now hear - at least on 80. It was
reasonably directional and, although signal strength was way down, it was much
quieter than the sloper. I was able to pull European 80 meter signals out of
the noise with the EWE that were not copiable on the sloper. Performance on
160 was never better on the EWE than the sloper.
Just before NAQP I disconnected the NE EWE and hooked up the SW EWE instead.
Performance was much poorer on 80 and, as somewhat expected, on 160 as well
when compared to what I'd been experiencing with the NE EWE. Before, during
and after NAQP both of the slopers heard much better than the SW EWE.
A few weeks later (and in a few feet of snow), I erected a ~200' terminated
Beverage oriented NE. I put the ZJ Beverage Box on it and ran ~200' of RG-8x
to the shack. In some instances the NE EWE was a (very) little better that
the Beverage, but in almost all situations the short NE Beverage out performed
the NE EWE.
In order to continue the investigation (and in an effort to hear JAs on 80!),
I reversed the Beverage so it was now oriented SW. When directed to the SW,
the Beverage now suffered from very high noise levels. I've never encountered
it here before, but it sounds like I have line noise towards the SW/W.
Although the SW EWE was not a real good performer, it did reject the line
noise better than the SW Beverage; but the slopers seem to hear better than
either of the SW oriented receive antennas.
The bottom line here: The EWE works - not great, not always better than a
Beverage - but it works. For those with limited acreage for adequate
Beverages, the EWE, I think, would be a very worthwhile investment for
improved reception (at least on 80).
I'm planning to move in the next few months and I'm thinking about new
antennas on a green site. If I build on the property I want, my current plans
are to assemble a four EWE array similar to that described in the follow-on
QST article. This would be in addition to two ~500' Beverages oriented East
and West.

not to mention the consequences of getting into the way of a low flying
plane. in this area i am in the path of a low level air force training
route, i even notified them before putting up my 150' tower which their
a-10's promptly surveyed the next weekend giving me an excellent air show.
getting up to 300' would put me right in their path, not to mention what
might happen if it got away and went higher into the normal pattern of
surrounding airports. i think there are still rules about going above
200' which probably would be pointed out very quickly if a monster
floating antenna caused any damage to a plane.

Hi Guys! Here's my experience with the EWEs:
Last Summer I put up my first EWE using the 160/80 combo EWE as described in
Feb 95, QST. That design is: 15 ft up, 38 ft across, and 15 ft down. I
terminated it in a 830 OHM resistance and used the K2ZJ box at the
ground-mounted feed point. Both ends utilized 4 foot ground rods into good
ground conductivity clay soil. It was directional to the NE.
The results were superlative. Not only on 80 but 160 as well. I was able
to hear stations that were in the noise on my transmit antennas (see
signature, below) on 80 & 160. I also compared the signal strength to my
transmit antennas. Those EWE signals that were coming in from the direction
of reception of the EWE and the direction of reception of my transmit
antenna (more easily determined on my rotatable 80M antenna) were always
equal to or less than those on the transmit antenna.
But, signal strength is not the reason to put up a EWE. Signal to noise
ratio is.
I also had an 8-slinky Beverage that was aimed NE with which I compared to
the EWE. The slinky was never better than the EWE. Sometimes they were
equal. They both reduced the noise levels on 80 & 160 and improved the
signal/noise ratio.
With these results under my belt, in October 1995, I installed 3 more EWEs,
completing my last one the day of the CQ WW SSB CONTEST. These three were
built using 12 ft sections of aluminum tubing attached to my wooden fence
rails and adding 3 ft of wire to them to attach them to the K2ZJ box and the
terminating resistor. They were installed for reception South, East, and
West. The E and W EWEs are back-to-back on a fence line and about 30 feet
from each other. These two are positioned such that signals from the West
encounter the West EWE before they encounter the East EWE, and vice-versa.
Again, results were fantastic, and measurable. There is about a 15-20 dB
front to back ratio between the E and W EWE. I have a switching setup where
I can punch a button to switch from EWE to EWE. Likewise with the South
EWE, I'm seeing a 15-20dB difference in signal strength between the NE and S
EWEs on some signals. There are times that I can't hear Southern DX
stations on the E,W, or NE EWE or Slinky that I can hear on the South EWE. I
used the W EWE to receive JAs on 160 this year. They were much louder on
the EWE than on my inverted "V" xmit antenna (which is broadside NW/SE).
I do not have the space in my yard to install a classical Beverage antenna
so, I do not have any comparison to make there.
I found out that, due to a local broadcast station, my NE EWE was having the
K2ZJ microwave oscillation problem (that was discussed on the Top Band
reflector recently). I now use a non-amplified K2ZJ box on that antenna and
the problem went away (as the theory says it would).
I am very happy with my four EWEs. Without them, my 80 and 160 CONTEST
scores would really be suffering.
I should add that I read in someone's response to this thread, that they
considered the 160/80 M EWE design in the FEB 95 QST a "compromise" design.
That is an incorrect classification of this non-resonant type of antenna.
The designer merely used convenient heights and lengths, analysed several,
and came up with a design that produced acceptable results (modelled) on 160
and 80. That's far different from a resonant antenna "compromise" where the
antenna would be electrically shorter (or longer) on the "compromise" band
than on the "original", or, "basic" band.
I will be glad to relate other anecdotes regarding my EWEs, if anyone wishes
to have more info.
73!

Thanks for the offer, Brian. Actually, since I'm planning to use the latest
hi-gain coax, the distance between the west coast and Maryland should be a
great help. With a gain of about 1 db per mile and an input of 20 mw, much
of the east coast would be vaporized. That is unfortunate of course, but
hey, life is full of tradeoffs...
