so ive got this arrow 146/437 yagi that ive been using for satellites and the 2m side is fine but the uhf is showing like 3:1 swr. checked all the connections twice and theyre solid. anyone else run into this with these antennas? starting to think maybe i damaged something during assembly but it looked pretty straightforward

using a diamond swr meter if that matters. both sides were working fine when i first put it together last month

had the exact same problem with my arrow a few years back. turned out one of the uhf elements had worked loose even though it looked tight. try wiggling each element while watching the swr meter, bet you'll find the culprit real quick

arrow antennas have this issue sometimes with the boom clamps not being tight enough. also check that you didnt accidentally swap any of the element lengths during assembly - the uhf elements are pretty close in size to some of the 2m ones and its easy to mix them up if you took it apart for transport
