Excellent for amateur radio
I am probably one of the first people to purchase this antenna.
First, very easy to put together; screws are a bit of challenge - there are 2 types; the larger ones are for the boom and center holding the elements. They tend to strip - recommend try to get the hole 0.2mm larger. The second set of screws are specifically for 2m ele extensions; they are mild steel and prone to rust; best to replace with aluminium screws which i did.
Matching is pre-tuned; even though this was a negative; i found the swr is well across entire spectrum for 145/440; on 2m - SWR was 1.3:1 and 440; it was 1:1. Really good. Nevertheless, a flexible matching stub will be a welcome modification.
I mounted it at 10m height and feeding with rg-58. Excellent. I am able to hit repeaters and hold over 100km away. I am also using Retevis RT-95 dual bander with this antenna.
Recommend it if you are intending to use it for a base station or extend it for satellite use.
