TWAYRDIO Yagi Ham Radio Antenna,Dual Band 2m 70cm VHF UHF Yagi,High Gain 8 Elements GMRS Vertical Base Antenna for Repeater System,HT Scanner,Satellite Work

Arrived well packed and works great

After installation I ended up with a 1.14 VSWR match on the 70CM band right out of the box with no adjustments using 50 feet of LMR400 Coax and a RT97L repeater. Light weight and easy to put together. So far, it seems good.

I had had this antenna up on a 30' ttower for 6 months. Upon purchase the SWR was marginally adequate, but never great. It was about 2.4 on 2 meters and a little less on 440.. The SWR on 2 meters then went over 4 after a few months. It is impossible to improve the SWR with the gamma match. I should have returned it initially. The antenna is cheap and based on my experience will not last.

The quality of the antenna is very good. However, do not begin to assemble until you separate not only the antenna parts, but also the screws. Half of them are sheet metal (the slightly larger to secure tubing to frame) and machine screws (smaller) to hold the elements together. They have Phillips heads, so please use the appropriate and right size screwdriver!!!! If your screwdriver has a worn head, get a new one first. It requires some pressure to secure the screws, and you do not want to strip the screw heads. 73, K8KIZ

Good stuff

Pretty agreeable for the price - extremely simple assembly, maybe 2 minutes. There are numbered elements that go in the main assembly and six unnumbered extensions just for the 2m elements (the only ones with shoulder inserts, they are all the same length). Instructions were simple but clear - hard to mess this one up! Have a smaller driver handy for the extensions so that there's no risk of stripping anything out. Nothing is threaded to receive hardware but the holes are just right to hold tight so long as you aren't over-tightening anything. NanoVNA measured minimum SWR of 1.381 at 140MHz and 1.133 at 450MHz right after putting everything together. Looking forward to further testing and tuning.

The antenna had been previously installed, as shown by the scuff marks where the U-bolt was to hold the antenna onto a pole. Furthermore, the U-bolt was missing from the product sent to me. The screws and their holes are tiny, and are meant only for a permanent one-time installation.There was no company name for the product. The q-code and web link didn't work. The video did not show how to assemble the product.On the plus side, although the diagram was useless, the parts were marked, and I was able to lay them out from the photograph.

Works great with my HT for working ISS and Sat comms on a tripod. 73 de KF8BTH
