This "IS" a very interesting antenna . Afriend of mine from London Ont. has been driving me nuts lately to build her an indoor apartment antenna for her new HDTV . I was stumped on what to build her till I saw this .
Thanks 300ohm .
Taking the dimensions in the specs, I began playing around with it on Nec . You can really change the patterns easily throughout the frequencies and achieve a nice omni pattern by playing around with the hieght and width . I opted to stay mostly directional for her window faces towards the London towers and I ended up with 8" square , 1" feedpoint in middle of the antenna.
The SWR is alittle high but I`m sure the experts could fix that. So going by my figures and using the Loss formula it would be a pretty low gain antenna. However this is only meant to pick up stations less than 8 miles.
VHF showed extremely high SWR.
So with some time to kill and less than 40" of 1/4" solid alum. I bent one up , drilled two holes , put in 2 brass #6 bolts and 4 nuts for a balun. Very cheap.
Nice flat antenna that you could cover with endless ideas .
For the heck of it I hooked it up to the LG , hung it in the window , @ 10 off the ground, through obstructions , I was impressed with what it picked up . Highlighted below is what it recieved. most signals were pretty snowy but was there.
31 & 10 (VHF) I could get perfect picture . I only have 1 digital avail. but couldn`t get it. This coming weekend will tell how it does in the city.
