Hey 5 , about the two bay I built on the PVC. I recently removed it from the mast. We get heavy wind here and I noticed that the antenna was catching too much wind and swaying in a big way. I plan to reduce the wind resistance by replacing the reflector backbone with 3/4" aluminium. I also thought of drilling 1/2" holes in the element backbone to help reduce the wind loading. Just thinking. M
The PVC lumber comes from Lowes home stores. Other sources are Home Depot, and some lumber yards. Now that's in Florida, PVC trim is very popular for trimming exterior doors and windows, it never rots. It usually has its own section in the store, near the regular trim boards. In your area the demand may not be as high as it is here. Some have told me that they can only find it at lumber yards. There are alternatives, mostly dimension lumber made from recycled material and such but like you said not as nice. Some terms are, PVC lumber, trim, plastic wood. Material is always a problem. Some guys can buy rolled aluminum rods at their stores yet my stores have no idea what I'm talking about. Keep hunting, you might find a good alternative.
@@cosmicantenna9244 ok we have a Lowe's about a half mile from home. I swear I walked up and down every isle yesterday looking for some. They had PVC fencing but no sold boards. I had a few feet of poly deck boards left over so I cut those to use for now. Have you ever tried to add another 7"x7" 90 element section ? Or using 3.5" 90 sections inside the existing elements?
Adding sections to the Hoverman disturbs the phase sync of the signal, making the element larger or smaller never worked for me, couldn't hold a signal. I saw a guy made a 7" Hoverman then mad a 3.5" and mounted it in front of the 7. All it did was interfere with itself !?! Looked cool.
@@cosmicantenna9244 I've considered both problems you mention, I'm less concerned about being out of sync, but the element size sure would increase thus changing where it's sweet spot in the uhf band would be. This is why I ask before I act as your the expert Thanks you once again I really appreciate the input
@@cosmicantenna9244 there is a guy on RUclips that used 1/2" copper pipe w 45 & 90 degree elbows, and it worked really well if he's telling the truth he was pulling in stations he claimed to be 100-120 miles out and the antenna was just sitting in his living room. Looked like a hooverman on steriods
I like the simplistic approach when making an antenna insulator. This is probably a 50 year warranty on the insulators.
This is almost exactly like I build my antennas. I just use another section of PVC board for the backbone, though.
I built a 2 bay on PVC here

Were did you the.pvc.sq. stock??
Lowes, home Depot.
It's house trim. Sometimes it has texture
@@cosmicantenna9244 Great video - Thank you!
One thing though, what size and length screws did you use on these insulators?
Cani ask where your sourcing the PVC board? I've been looking locally and can't really find a material this
