Now that we all know that 80m loops cannot out-perform dipoles, I would just like to remind you that bumblebees cannot fly (according to theory). 73 de Paul K9OT in SW Wisconsin _____________________

I have been following this thread with great interest. Firstly, I appreciate the fact that no one has appointed themselves as the "police" and whine that this is not ten-tec related in attempt to squ

Hello Paul!!!! Regarding 80m loops. I have two orthoganal 80m loops and an inv V for 80m. I was told by several DXr's that I needed an inv V and that it would outperform the loops. The V hasn't been

Outstand information Bob, thanks. Your (dipoles) results are exactly as to be expected, but I have a question about the two dipoles: It is said that low dipoles lose their directional effect and beco

Having never had the good fortune to have tall antennas, I can verify (at least in my experience) that low dipoles for 40/80/160 are pretty much omni directional. I'll give you a for instance. I live

Noel, I would suggest that you either 1) take the ARRL Antenna Modeling Course, as I am doing right now, or 2) get someone who is a competent antenna modeler to do some analysis on the antenna variat

As a general conclusion, yes the lower dipole in an inverted V configuration does appear to more omnidirectional. The higher configuration is clearly more directional but is difficult at best to make

Hi Noel. Yep, a lot of people knock the good old horizontal loop for no good reason. I'd like to get my loop up at 185ft! I have a non resonant horizontal loop about 156ft total wire length at 25ft A

That's what I've been told too, Bob.. More wire = more contacts. A real G2 and a couple of real G3's told me that it's a good rule of thumb. So that's what I did, no measuring...just put as big a loo
