Best antenna will go to mom's attic.
This is a discussion on Building these antennas this weekend within the DTV | HDTV Reception and Antenna Discussion forums, part of the Over-the-Air (Antenna TV) category.
Best antenna will go to mom's attic.
Awesome. Real world tests results too.
My money is on the McLapp.
Just one tip:
If you want to get better low UHF and/or VHF-hi, make the elements on the bowtie 10 inches. You can always trim some off, but if you want to add length later it means a complete re-build. If you will lose a bit of gain on the upper UHF channels, so it may not be an acceptable mod in your area.
Well the VHF seem to be coming in pretty strong on the 4 bay that is up here now (NBC 4 comes in great and PBS on 2 even)
and I already made the whiskers. I just have to solder and staple. I have a bunch of CM 9444 baluns coming too.
Home Depot sells these planks of polar for about $4 that are 1/4 inch thick and with a few wire staples it comes out solid. (hopefully they do not interfere.)
It's a nice quick project. I'm thinking the thinner wood also reduces the need for PVC spacers also.
I have all the line dimensions figured out that will touch the wood (after some geometry) so I can draw them and line up things perfectly.
Luckily, they have a big roll or 10 AWG mag wire at work that no one uses that I can borrow from.
I think the Hoverman is more difficult to manufacture properly, and thus my money is on the Quad Bowtie.
I'll take a look at that again with the frequencies.
As far as the Hoverman being more difficult, why is that guys? Just two wires and 90 degree on most angles.
It has to do with straightening wire and multiple bends in one longer piece of single wire.
antenna and the other being a Gray-Hoverman antenna.
I got those bends pretty good and I draw the proper lines on the wood to double check.
I see now about channel 7. That is my lowest frequency. I didn't realize what "real channel" was. I thought I had to go down to 54MHz.
I just spent hours on a few sites to make sense out of the channels I'm getting.
This site is a big help here:
The Gray-Hoverman is definitely a great design and is probably superior overall. I have the Antennacraft version that is designed for channels up to 83...and it is fantastic. One nice thing about it besides it high gain on UHF is that it is isnt very directional on lower UHF and thus can be used in a situation where high gain in one direction is needed but you are trying to capture some higher signals off the backside....without the need for a rotor.
My point is, never count on the promises seen in antenna ads. Physically testing different antennas is the only way to know which one is best at your particular location.
Well, I will build one of each and see how it goes.
Here are the channels I watch with the current 4-bay (9.5 x 9 no reflector, no PVC)
That should be named "mychannels", not ny

I bent the 90 degree angles on the GH today by drilling a hole close to the size of my wire near the edge of my work bench. Then pulled each proper length from under and hit each 7" length with a hammer the proper direction. Nice idea. All built. I will compare signals this weekend with current 4 bay (with the connectors on the whiskers) then build another 4 bay using this stable method and compare that.
Well, here is tonight's test. My new GH Vs my original McLapp with the connectors on the whiskers. The first McLapp is a month ago and possibly without a splitter to two other TV's. The next test was an hour apart today. Not sure what is going on with 25-1 (ABC from West Palm Beach) but the McLapp had 29% before trying the GH, but gone when I switched back. Maybe it was tilted slightly. But it is a little cloudy out.
So, looking at the "Real Channel" column. I have less signal on the lower frequencies (real ch 13 and below) with the Gray-Hoverman (GH).
I will build another McLapp tomorrow using the same build technique as as the GH as in the diagram in the first post, to compare apples to apples.
