|Customer Reviews for the AV-18HT.|
|From: Frank Wolfe NM7R|
|I bought my Hygain Hytower used in 1983. It has decorated my yard, here on the coast of Washington State since then. Instead of radials, I chose to install six (6) 8-foot ground rods around the concrete base for a ground system. The earth here at the beach is sandy and moist all year round, with a water table never farther than a couple of feet below ground level. The antenna has performed wonderfully all this time, surviving winds over 100-mph about every second or third year.|
I was lamenting that I had no antenna for 12, 17 and 30-meters, and recently ran an SWR plot for these bands, just to check. Thirty is still not usable, but I was pleasantly surprised to find that 12-meters loads with an SWR of 1.7, and 17-meters at 1.3. Although SWR is not the whole story for antenna performance, I recently worked E51WWB in the North Cook Islands on 17-meters with 100-watts for a 59 report both ways.
Thanks for building such a rugged, reliable, great performing antenna.

|The av-18ht ,was my only antenna,for 32yrs. I repeat 32 yrs of service. We over the years have had winds upward of 65-mph plus. Finally, the top 80m. Radiator had enough! It was bent to whereby causing a small slit like in it. It was not feasible unfortunately to Repair it. Bottom line: this is the best antenna ever designed, and manufactured by hy-gain!! I Sure miss you "big guy". 73's to all.|

|I have had my Hy-Tower (AV-18HT) up for 5 years in Tornado alley (central Oklahoma) and it is my primary antenna. I did design, fabricate, and install a custom mount to erect it on top of an all metal barn. I have no radials just the metal barn as counterpoise and it works very well indeed. Rather than having to tie in a large portion of the roof structure I elected to guy the antenna at the 24 ft point which is the top of the triangular tower portion. I used Phillystran for the guys. To lower the antenna for tuning I just drop the west side guy and lay it down on top of the roof ridge. |
As I am in my 70's I built a simple lowering fixture that uses a small inexpensive hand winch from Harbor Freight to make single handed lowering and raising really easy. I have the 160 meter kit but haven't installed it yet. My 160m kit is not the one with a coil but the one with a 40m trap and a long piece of wire to be attached at the 24 ft level (top of the triangular tower section.
You can view my installation on my QRZ.com page. 73 all!

|My hy-tower was originally purchased by my dad about 1972, and installed at his home. Following his death in 1993, I took it down and installed it at my QTH for about 20 years. Following the recent building of a new home, I moved it again, and set it at the new QTH. It has recently received a coating of Polane-T and is looking very good. My swr is no more than 1.6:1 and any of the 5 bands, and I have been working Europe the last few days. It has been great that whatever base parts I needed to support the relocation have been readily available at a minimal price. A great antenna!! |

|Installation of antenna is time consuming. Two person stand up is difficult. Used come-a-long to stand up antenna. Some bracket holes were tight so I reamed out. Bracket placement for stub was incorrect in manual but I was able to place them properly for tuning. 15 meter stub is only one I had to retune. Ordered 17 meter stub which I did not get. Did not ship with antenna. Antenna performs well. It is pricey and you should expect to add $500.00 more for concrete and ground rods and wire for grounding and radials. I am going to add 120 radials. Wear gloves antenna mast has sharp edges. |AR-40ROTATOR, FM-TV-COMPACT ARRAY, 3 SF WIND LOAD$349.95
