Incredible quality and communication and price Time Owned: 3 to 6 months.
Well had this up for a short time to test at only 20ft and is outstanding and construction is flawless in my view point. I was so impressed I ordered another Antenna from Justin a 2el 10m Quad. I have had a lot of antenna's over the years to keep my interest in the hobby but now getting older so I am now narrowing down a few antenna's to carry into retirement.
I truly believe the Quad will be one of those antenna's once it arrives it takes about 3 months from order to doorstep on the antenna's I have ordered don't think that would be the case for all orders. I appreciate the time Justin takes to respond and clarify any inquires a fellow might have. If this 10m 2element quad is as good as the Moxon I will add one last antenna to the bunch from InnoVAntennas and I will be Happy Ham for many years 73's all take care.

Light weight with good performance. Time Owned: 3 to 6 months.
I installed an InnoVAntenna, Mox-14, 2-element, 20-meter monoband Moxon Yagi in October of 2019 and have it mounted on a Penninger Tipper mast at 35 feet (11 meters). This antenna weighs about 25 lbs. and the whole mast with antenna is raised and lowered using a brake winch on top of a 6"x6" pressure treated post. I couldn’t go much higher because of power mains in the air along the back of my property, and 35' is about the maximum practical height for a tip-over mast using aluminum tube and a 25 lb. load. I will write a separate review for the mast. The whole mast is rotated using a Yaesu rotor.

The antenna appears to perform to specifications covering the whole 20-meter band with less than a 1.3:1 VSWR. I also have three, 55 ft long doublets fed with open wire line and a remote tuner for 40 through 15 meters at 38 feet for A/B comparison. Each doublet is the side of an equilateral triangle and I use a relay network to switch between them for the best signal strength. My doublets work very well on 20 but the Moxon shows about 3 - 7 dB improvement while receiving during a rapid A-B switch between the Moxon and doublet antennas. The higher number comes about in the directions where the doublet signal beamwidth is down -3dB, which are crossover points between the doublet switched elements. I used a step attenuator to obtain these estimates along with my TS-590S S-meter as a relative-reference indicator.

The Moxon has a great front-to-back ratio across the whole band with it exceeding 30 dB at the center but remaining in the 18-20 dB range at the band edges (measured at 35 ft AGL). These numbers can and do vary with different angles of signal arrival. The high front-to-back ratio is a big help reducing local noise pickup and rejecting QRM, especially here in the NE United States with so many strong U.S. stations to my south and west. Receiving is improved not only by the gain but also the improved signal-to-noise ratio that exceeds the gain by a fair margin in some directions. Justin Johnson, owner of InnoVAntennas, claims his Moxon design is optimized for each band and I believe it because of the great performance, and because the actual dimensions show somewhat different proportions than those obtained using the freely available Moxgen program for similar element diameters.

Now the 20-meter band opens a bit earlier and closes a bit later for me. During periods of QSB, signals do not dive into the noise so much and my TX signal is a bit stronger too. This antenna has exceeded my expectations.

I had no problems putting the antenna together following the manufacturer’s instructions using sawhorses for support during the construction. The quality of the parts is outstanding with no burrs and everything fits together as it should. I am particularly impressed with the robust mechanical design of the element-to-boom attachment using threaded plates as well as lock nuts. The stepped diameter aluminum element tubing supports its own weight without sag, as does the square aluminum two-piece boom.

Because the environment around my home limits antenna height, I decided to go with a monoband design so my antenna performance would not be further compromised, as might happen with some multiband designs. Twenty meters has been my DX band of choice during this long sunspot minimum. I have seen some hexbeams damaged by the severe weather here in the snow belt off Lake Erie where I live and feel this aluminum antenna will hold up better. It was also considerably less expensive than a hexbeam, has half the wind surface area and in addition, purchasing this antenna from the UK was no more difficult than purchasing in the States. It was delivered in 5 days with no shipping damage for about the same as shipping from a company on our west coast.
