| Antenna Question
I salvaged some gear recently which included this antenna. What was it used for?
Thanks, Jed |

That looks pretty slick!
Anyone try using them, any reviews other than what's on their website? |

Try them, then report back how good they are or are not. I would not be surprised if the bandwidth is very very narrow. But when you don't have room for a normal antenna whatever you can get on the air with is a good choice. |

Everyone always gets hung up on bandwidth and SWR.
My dummy load has a very broad bandwidth, and the SWR is an awesome 1.1:1. The noise floor is real low, too.

I've read they work miracles, or they're snake oil. Check out the Isotron reviews on eHam.net to see for yourself. I think the consensus is they make the feedline radiate. I've never used one, but I guess they're OK if you're severely restricted for antenna space.

I used a 40/80 Isotron for a while. They're not bad but certainly narrow-banded. To be honest, I think the feedline radiates more RF than the antennas themselves.
