Post by prettypolly »

Opek-hcs 100 inner rod measurements I'm looking to see if any body has a bang on measurement for the named antennas inner rod to get a decent swr between 27.415 and 27.555 please around 27.465 ,I've been trying for 3 days now up and down the the flipping ladders it's 1.3 low down on the ground but when we raise it the swr goes lower on the lower band when its up in the air but it's ok on the ground or 10 feet off the ground 😭😭😂

Pretty common with endfed antennas, where coax or mast act as counterpoise.
Mount it properly, I wrote some time ago in other thread how it should be done.
