Best place to buy a mast and stuff

Where would be the best place to by a mast and mounting hardware? I know Hope Depot sells some pipe but that is about all they got.

When I upgraded our system back for the digital transition in 2008 used 1-1/4 EMT for the mast I purchased from local electrical supply. Comes in nice 10 foot section, rather then the more typical mast sections in 5 foot. EMT has pretty think wall (.065") so works well as a mast. For the rest of the stuff purchased online from various suppliers. Don't know who is the best a decade later.

One item of advice, I'm using a wall mount on the gable side of the house. What I found over they years is the mount itself is strong but the extension that clamps to the mast is pretty flexible. I've had problems with it bending in heavy wind. I frabracobbled a supplemental support from 1/2" EMT and secured the mast to the roof eaves a foot or so above the wall bracket, that has solved the problem.

Use chainlink fence TOP RAIL. Works perfectly, and it's swaged so they fit together to get longer than 10ft. Of course, if you do longer, you'll have to have it clamped and/or guy-wired every 10ft.

I like the way you tilted that UHF bowtie antenna upward. I may try that... Any tips on what to use?

Not sure if it helps reception. I was not about to do a scientific test with and without tilt, but I figured it couldn't hurt here in terrain challenged NH.

My first idea was to have an electrical shop simply bend the conduit, but no one wanted to touch it. Then I tried muffler shops but they thought their bending rig would crush the EMT so also a no-go. I ended up building a box out of four angle brackets, needed longer bolts at the top. Has been working find since 2008 and several ice and wind storms.

If you want the gory details I've posted more details on my web site:

And here I thought I was being so clever using EMT rather then "real" TV mast.

I've got a tilting bracket on my Stellar labs VHF hi antenna, and I might get lucky and be able to swap it out and use it on my 8 Bay UHF. I'll have to check that out. The tilting didn't do anything for me on VHF... UHF I think it would work better.

Even an 8-Bay has a vertical 3dB beamwidth of about +/-15 degrees. Tilting the antenna a couple degrees up or down won't affect the signal in the main lobe. Reports of super sensitive pointing in any direction is likely interference coming from some other direction being placed in a sharp null in the off axis antenna pattern.

I have 2 stations that can be received occasionally by slightly off pointing the antenna and placing a co-channel interfering station in a rear null. The pointing is very sensitive (+/- 1 deg) even though the signal in the main lobe shows no change on the spectrum analyzer.

I don't know what EMT is. But there is pipe at Loewes and HD that will work if i can stick it in my C6 Corvette. I got the mounting hardware at Lowes. I am cutting cable soon as it is $200 a month with the phone and internet. So both are going and i am keeping my internet. I have a ANT set up for my bedroom OLED, but not the living room TV. I have a extra ANT that worked fine when i tried it about 2 years ago. Just gotta get it done.

Sorry for the technobabble. EMT, electrical metallic tubing, otherwise know as conduit. The stuff we are talking about is called thinwall, there is thickwall, that is more like water pipe.

10' shouldn't be too bad if you have a hatchback or a sedan with fold down rear seat. Put a blanket on the front windshield, bungee cord the trunk and depending on how far you need to go tie a red flag to the conduit hanging out the back. Corvettes's are out of my league so have no experience using them to haul building supplies.

When picking it up be sure to double check pipe diameter, trade size for building products does not reflect reality.

Seems the signal meter was low for many chans so i added a old power booster and that seems to bring the meter up to full power for most chans now.
