... Since I have about 80 feet of it sitting in a roll, I'll probably use it to build the hexagonal beam that I'm working on. I can't see any reason why it...
I have all the parts to start building and I've been reading the posts here about creating a parallel feedline. Is each driven element designed to be 50 ohms...
Hi Leo, and thanks for your thoughts. I have an original Traffie HexBeam 20m monobander and this inspired me to build a wideband version. The wire used on the...
I built this antenna last weekend. I checked it with my MFJ analyser, Highest swr was 2:1 on any band. Ihave it on a pushup pole at about 32 feet. Thease are...
Hello everyone. KI6HNB here. Name is Eric. I was wondering if it would be possible to build a 2 element hex beam for 10 and 15M only? Can I just eliminate the...
Hi Steve, what an absolute pleasure to hear from you... Well as the saying goes, 'if it's good enough for you, it's good enough for me!!!' I'll put an order in...
Hi Chris, welcome to the group. Just thought I'd chip in before those more knowledgable do...Yes PVC coated does make a significant difference to the wire...
Steve - The concern about the interest in insulated versus non-insulated velocity factor is interesting. However - In trying to figure out the formula for the...
... EZNEC does a pretty good job with insulated wire, but only if you know the dielectric constant of your wire's insulation and, of course, the thickness, but...
Phil, Each band presents a nominal feedpoint impedance of 50 ohms - it's a 2 element parasitic beam, not a dipole. There are some complex processes going on...
Hi Charlie, There may be some misunderstanding here about the constants involved. Let me try to explain. Insulation causes a reduction in the Velocity Factor...
Hi Eric, If you are building my broadband version, you can just omit the unwanted wires. If the shape of the support structure produces greater 10m/15m...
howdy! Yep the hex with insulated wire works great! Mine has been up for over 2 years. However sometime before the garden goes back in I need to make the BB. ...
Steve - Thanks for your response and I am sorry I confused you a bit. My real question deals with this paragraph out of my original message: "However - In...
Charlie, Hopefully the following points will address your questions: 1) You should not expect the Driver and Reflector lengths, multiplied by the design...
... Thanks, Steve. That explains it very well for me. How do you feel that the excursions from 50 ohm cable to the connecting bolts (pigtails) and the size...
Phil, You're right that the "pigtails"; have an effect, but it's very small provided you keep them short. The impedance discontinuity has negligible effect on...
It looks very good removed from the box. I'm putting one together this weekend, starting in just a few minutes :-) Grant/NQ5T ... [Non-text portions of this...
... Finished it this morning. Went together without a hitch. Even with the base sitting at about 2' the VSWR on all bands was generally good enough to try it...

It is a very 'Cute" antenna. At least that is how I described it to my wife.... And then It went up in the air. Three years later....she does not agree. But ...

Hi folks, I gave up on attempting to build a 3 el hex beam. It would have required my obtaining a larger diameter set of spreaders. Also, the size difference...
