Superior product
|
Time owned: 3 to 6 months
|
My system is optimized for RDF and uses 21 foot elements with 80 foot spacing in a four square configuration. Compared to two 560 foot reversible beverages it has a similar pattern and S/N is better about half the time on 160M. Otherwise, the S/N is about the same. On 80M the Hi-Z four square S/N is better most of the time compared to the beverages.
The large elements provide higher output than 8 foot arrays and that is an advantage.
Customer service is excellent with same day or following day responses from emails sent.
Documentation is very good with considerable reference material on their website.
Highly recommended.

Triangular Array - A Wonderful RX Antenna
|
Time owned: more than 12 months
|
I live on a small city lot, no more than a quarter acre. I have tried over a dozen receive antennas over the years looking to improve the all important signal to noise ratio. Nothing gave a meaningful improvement. Along came the 3 Element Array, so I thought I'd give one a try.
Everything about my situation is a compromise. I can't get a 40 foot triangle with equal sides, one of the elements is 3 feet lower than the other two, the corner of the house blocks the line of sight between two of the elements, two of the elements are near a metal fence and one of the elements is within 50 feet of my vertical. Not a pretty picture.
Still, the system is highly directive on 160 meters where I spend most of my time. It provides a very good improvement in signal to noise ratio over my vertical and has truly uncovered another layer of signals for me. It REALLY does work, even with all the compromises in my situation. I am amazed at its performance and am VERY happy with the decision to install one.
I am able to run the legal limit with no harm to the array, even though the array is no more than 50 feet from my TX antenna - a great feature.
I was very pleased to find the array is highly directional on other bands - right up to 10 meters. It's just incredible.
There is a REAL solution for city lot owners with challenging situations. I highly recommend this array.

Ecellent product and Service

I put up the Hi-Z 160 8 antenna receive array several months ago. I have had very good results with the array. The Hi-Z has usually outperformed my Beverages ( though not every time), and is usually as good if not better than my 4 square transmit ant. I had a minor problem which required service which was done in 4days! I am purchasing an 80 meter 8 element array to nest inside the 160 circle. If I did not have this array I would not have had the H40KJ in my 160 log!!

Makes my 160m life easier
|
Time owned: 3 to 6 months

The real test to beat noise is surely at equatorial zone like in YC-land. Ordered one unit of Hi-Z 4sq RX Array and -after installing the system in Mt Malang (1050 m ASL), West Java- it made my 160m life easier. Tnx to Lee for cutting the phased delay line coax. 73 de Jo, YC0LOW

HI-Z RX PREAMP
|
Time owned: 6 to 12 months
|
This review is for the hi dynamic range preamp that Hi-Z offers in a kit or built. I built mine- took perhaps 30 minutes. It is part of my Beverage antenna control system. I followed the preamp with a Mini-Circuits 2X power splitter- allowing me to use the Beverage on my IC-7700 and my Cubic 103 without switching. No signs of overload. Easy to build kit and very well documented//designed. Excellent value aleternative to the high priced products.

Works great - low cost - well built
|
Time owned: 0 to 3 months

My array is spaced 70' on a side. Using the switch box, control box, antenna pre-amps and the inline preamp. 20' verticals from conduit. Works fantastic on 160 from out here in Arizona. Also works very well on 80 - 30 and even at times is better than my stacked 3/3/3 yagis on 20 (narrow beamwidth produces nice S/N at times). Well built - well protected and very well priced - more than a 50% savings off the competition.
Purchased with the intent to use it primarily on 80 with hope for 40. It works great on 80 - the 2el beam at 130' works better on 40 (although I believe during the spring/fall season, with higher static levels the array will compete with the beam). Signal level on 80 is almost identical to my xmit antenna (rotary 76' long dipole at 136') but the S/N is better on the array.
Then I tried it on 160.... having never operated 160 I was intrigued by its performance there. I installed (well - actually AB7E installed it for me) a 100' vertical section inverted-L off the tower. Installed 16 radials ~ 0.2 wave long. First night was Dec 26... since then I've worked 60 countries on 160 in 2 weeks time with 30 confirmed already through LoTW.
Check it out - you'll be happy with the savings and performance!

I am using a FOUR element RECEIVE array
( 80 ft on a side )
designed by Lee K7TJR in Oregon. Each
element is 20 ft tall ( user provides this part)
Lee provides pre-amps for each element , a center
switching and phasing box and a controller for the
shack - this SYSTEM has been a huge improvement for
me over the prior K9AY RX system. I highly
recommend this product - parts are assembled or
if desired in KIT form- pricing is much less then
the competition !!!
