The technical committee is current arranging an lift so we will be announcing the antenna party soon. We still need to do the final check out and tuning which should be done within this next week.

So come on up to the club house this next social to get a good look before it goes up on the tower. Plus learn how it works and how it is put together. See how it might be good for your station if you have limited space.

A hex beam antenna looks like the loops are a continuous loop but they are not. The driven/forward elements make an “W” shape dipole with the feed point on the center post. The rear element has a insulated Kevlar string separating it from the driven element with a small gap. So you can see it is not an continuous loop of wire. The sizes of the loop goes from small { 10m } to the larges loop { 40m } with each loop doing a different band. Our antenna will cover 10, 12, 15, 17, 20 ,40 meters.
