SteppIR at 25mph

This is my antenna st 25 miles per hour wind. We had wind gust up to 50 mph.

The wind was 25mph with the gusts up to +50mph

Thats rediculous, my Mosley doesn't even move like that in a Hurricane.

I'm In a very high wind area here, so I elected to go with A cushcraft MA5B on HF , A cushcraft 20 ele. Twist for 2 meters. A discone off the side of the tower . A pair of eggbeaters for sattellite work on a common boom mounted to the chimney, A 6 meter vert. mounted highest on the tower.There is also a center fed zepp for multiband HF ops. and a 520 foot loop for 160 mtrs.

@InspireImages of course fibreglass is going to flex more than aluminium, that's probably why a SteppIR will withstand stronger winds than most other  aluminium beam antennas such as the Mosley that everyone seems to rave about.

@BongoBob6969 And you have got first-hand experience of using a SteppIR?

[BobP600]

Remember, the elements on the SteppIR are FIBERGLASS. A metal strip INSIDE the fiberglass is the actual radiating element. These radiating elements are extended and retracted using stepper motors to control the length. That is how they work on all bands. Neat idea. I'm surprised they don't have a truss for the longer elements though.

That is why us radio amateur's keep a very close eye on the weather if we have towers with larger antennas in our back garden.

SteppIR is junk. This video shows how tenuous it is in the wind. That's awful. Imagine if it were double the height and the wind was stronger.

Junk, junk, junk. Buy a Mosley. They NEVER fall down.

I think it was rather strong, moving was oK. flexible is stronger than ridit.

[symtron]

Wow. Wonder if the movement would have been less facign into the wind?
