"And I had nothing to do with your leaving this board last year. That was your own choice...well that and another poster you were always at constant logger heads with."
It seems that almost every time i would post something back then, there was ALWAYS someone who thought they knew more than me. I don't claim to be the TV reception guru, but I do have more experience in this arena as a 10 year TV Broadcast Engineer, who was involved in the DTV transition from the very beginning, than most everyone who was "DISSING" my posts back then. I looked back at some of my old posts, and you are not completely innocent either, regardless of your denials.
My post on loop antennas is NOTHING even remotely like my revolutionary antenna design that I am trying to get a patent on. This is simply the basic design of the clear stream C-2, and has nothing to do with my own antenna design in any way WHATSOEVER !!
The C-2 has no capability to receive VHF signals in either of the VHF bands, where as mine is capable of receiving signals in both VHF bands. I am currently receiving channel 3 (Actual RF Channel, Not the virtual channel) at 20 miles from the transmitter with my antenna, using it INDOORS and it only measures 12 inches by 24 inches. It's main focus is on the UHF band, but it performs well on both VHF bands too.
I only posted the loop drawing to show roughly how the C-2 is designed since the thread topic was loop antenna engineering, and so experimenters can try different versions of it for themselves. I built one of these 3 years ago, and it only cost me the price of some small hardware, versus the $100 plus retail price of the C-2. My intent on this thread was to help do it yourself'ers to try this design and maybe improve on it and save a dollar on an antenna that performs well at UHF channels for mere pennies.
I was trying to share the Luv, but this quote "Double loop antennas are nothing new. I even found a pic of an old triple loop antenna", and "I think one would be hard pressed to find any good ideas for the use of a loop antenna since they pale in comparison to other UHF antennas such as yaqis and bowties", is simply not true.
The double loop antenna such as the C-2 with a back plane reflector added then becomes a very directional antenna, because as some may know, the C-2 is one of the best selling UHF antennas on the market right now, ( TV Technology - January 18, 2012
) and my tests show it is very directional with the addition of the back plane reflector, and has high gain numbers with the addition of the second bottom loop. Even the single loop version (C-1) works fairly well as a city grade antenna, and is small enough to be used indoors.
I am not trying to stir controversy in any way, but I have built yagis, and multiple element bowties, and most any other type of practical UHF DTV antennas, and the double loop design is an innovative design with much engineering that went into its development, and it is an effective DIRECTIONAL ANTENNA. And yes, I do agree with your statement that omni antennas SUCK for DTV reception, especially in high multi-path areas such as where I live.
The irony here is that I have my own revolutionary antenna design, and I was only trying to be a participant an give this thread some new ideas, and I end up defending the loop design when my antenna is in no way similar to the loop antenna design in any way, and is far superior to it, and when my preliminary patent ( Patent Pending ) is granted, I will be glad to show it on here, and anywhere else I can promote it. I have two versions of it now, and am working on applying the concept to an indoor version also.
