CLASSIC BEST Time Owned: more than 12 months.
I have Had a TH3 mkII for all most 30 years. It still works as good as the day I put it up. I think it is one of the best built HF beams on the market.

Outstanding Yagi Time Owned: more than 12 months.
I have had a TH3 up for about 12 years now at the height of 40 feet. To knock on wood it's never been down since I put it up there. I operate CW only and it is flat as can be on all the bands. If I can hear a station no matter how well I can work it. To me for the money and a good used antenna to look for the TH3 MK4 is number one in my book. Nothing but good reports over the years have insured me that in 19,000 Q's they can't all be trying to make me feel good.

Excellent performance from a tribander Time Owned: more than 12 months.
This is the first 3 band yagi I have used. Previous antennas were for 10/15 meters including a HyGain DB1015 and a home brew 2 element quad. Generally with the DB 1015 and quad if I could hear them I could work them with a mere 100 watts. I find the same to be true of the
TH3 MK4, having worked such stations as VK0IR and ZL7AA. Lately, last 3 years, I have been leaning towards QRP and the good old TH3 MK4 has not let me down, again if I hear them I can generally work them. The antenna has held up very well in the windy Colorado weather, surviving several wind storms in excess of 80 mph. The SWR is very flat in the phone portions of 20, 15 and 10 where I like to operate. It does a very creditable job in the CW portions as well, but not optimized for there. Please note this antenna is mounted at a modest height, approximately 30 feet (9 meters). The instruction manual was very understandable and the antenna went together in short order, approximately 2 hours from start to finish (not installed just put together).

It has improved over the years! Time Owned: unknown months.
When deciding to install a roof top HF beam similar to the one I had on my parent's home in the 60s, I initially considered the TH3 Jr. However, talking to Barb at HyGain lead me to choose the larger MK4. Barb said that aside from power handling, the original TH3 and 3 Jr were similar. Whereas the "JR" hadn't changed since 1966, the regular TH3 had gone through four upgrades. Changes and differences I noticed were (1)SS hardware; (2)better instructions; (3)greater immunity to bandwidth/SWR changes caused by moisture on the roof/in the traps; (4)generally better performance. I can remember that working Africa in 1969 (SSB) was a rare treat. In 1996 and 7, while entering the pits of the solar cycle, I worked Africa with ease (same power, roughly the same elevation). In general, the TH3MK4 seems better constructed; even after 3 years, the boom and elements don't sag like the "JRs" did. The TH3MK4 isn't a Long John monobander but in general, I am very pleased.
