Pleasantly Surprised  Time owned: 0 to 3 months
May 2014

We are retiring and moving from the DC area to eastern NC in early 2015. So in preparation I sold my tower and beams early, but I wanted to stay on the air but wanted something that was not going to take a long time to install or remove so I decided on dipoles and a vertical. The dipoles are fan dipoles up in the trees and the vertical was the AV-680 mounted on a 14' mast out by the old tower base since I still had the underground coax runs. I made the mast tilt over to facilitate tuning.

I ordered the AV-680 from DXEnginnering as I have always had good support from them. Fortunately I had to use them once the AV-680 arrived. Upon unboxing the interior cardboard box that held the Matching Unit box rattled. The box was as the far end of the main box and directly inline with all the aluminum tubing with no additional protection. Somewhere in shipping the main box was probably dropped on that end causing the weight of all the tubing to drive into the Matching Unit, even though there was no external sign of being dropped it broke the matching unit. A quick contact to DXE and they took are of contacting HyGain on my behalf and had a new Matching Unit dropped shipped to me in a few days.

Other than that the assembly was easy, instructions were clear enough and all the parts were there. Using a AIM 4170 antenna analyzer made short work of tuning all the bands. Some took a lot more tuning than the manual indicated but they all finally tuned up fine.

So far the performance has been acceptable. Switching back and for between the dipoles (flat top at 45')and the AV-680 shows some interesting results. Sometimes both are equal, sometimes the dipoles are better, sometimes the AV-680 is better. On a few occasions I have been able to copy stations that the dipoles cant here, and sometimes the dipoles hear stations the AV-680 cant. Good reason to have both types of antennas.

I did make my own guy ring and guyed the AV-680 just for some peace of mind. Also after tuning up 80M I modified the 80M cap hat to work on 60M. Simply replace the 8 80M rods with 4 16" rods made from the spare rods Hygain sends. I have a 60M resonant element in my dipole and the signal reports follow my report above. So if you want a 60M vertical here is a simple mod that is easily restorable.

Bad Service From Hy-Gain/MFJ  Time owned: 0 to 3 months
Got one for our club station (W8DGN). We put it together and installed it in a really nice, high location. When we plugged in the coax to try it out, NOTHING! NADA! I called HyGain, and (Tom?) said it was a common mode problem with the matching unit, and we probably needed to re-solder the PL259 internally. No problem. We did that and again NADA! He said to return it. We did, and they received it on November 23. He said they don't repair them, but would send a new matching unit. Well, it's now December 20 and we still haven't received the replacement. We have a good-looking vertical 50 feet in the air and can't even use it. Thanks, MFJ! I'll revisit this review once I can actually have some experience with the antenna. I have an AV-640 at home and love it...

Sketchy  Time owned: 0 to 3 months
Not good. 15m is the only reliable band. Missing and wrong major parts received. Why only 1 review up to now ? Is there someone out there using this ant ?
Comments welcomed.

Still testing it, so far so good.  Time owned: 0 to 3 months
I bought this antenna back in January from R&L. Their service was top notch.

The antenna tubing has a nice finish, no sharp edges.

I had two minor issues during assembly. First, there was some missing hardware. Contacted hy-gain and R&L and the parts were received within a few days. The other problem was related to the matching box not showing to be DC grounded. After some troubleshooting, I found a cold solder on the inductor that provides the DC short. A quick re-solder of the joint took care of it.

The tuning of this antenna can be a little tedious. In my case, the antenna was resonating way below the ham bands and it took a lot more cutting than specified in the manual.

I don't have another antenna to compare its performance, but so far with 100W, if I can hear it, I can work it.

It works perfectly on 15 meters, covering the entire band with 1:1 SWR. My only wish is for the antenna to have better SWR bandwidth on 75 and 40 meters.
