Mounting a discone?

[macari77]

What is the best way to mount a discone on my roof/chimney?

I was thinking some good PVC or galvanized pipe wrapped to my chimney with some metal banding all the way around. Sound good or no?

You can buy different lengths of mast, thru about any hardware or home improvement place.

Go to Rat Shack (or anyone that carries it) and get a 5' section of antenna pole and a chimney mount.

Galvanized or conduit is too heavy. PVC would be fine if you weren't strapping it to a chimney in my opinion - the exhaust gases will likely degrade and may melt it.

Seconding the TV mast option. You can also check the 1.5" chainlink fence top rail sections - my preferred mast material, you can get stuff up 30 feet with just an eave support and one set of guys.

Chimney or universal mounts are still widely available.
I use 1" electrical EMT for my masts. Way stronger than a typical antenna mast. You could also use 1" galv if you really feel the need since the outer diameter is close to the same.
Up to 6'-8' I personally think EMT is plenty strong enough for the average antenna.

I made my own gable mount with a piece of 1-5/8" deep unistrut and strut straps.

Chimney mounts may be convenient however over the long run usually degrade in performance due to build up of soot and coax degradation due to heat. Another thing that can happen is damage to the chimney depending on how high you go up withe mast. Too much wind loading on a old or weak chimney can be an expensive lesson.

Just make sure the chimney is strong enough in the first place, i had a chimney mount when i first moved into this house, about a month later i went up to make a change and realized the whole chimney was broke loose at the roof level and moving, it wasn't doing that before i put the mount up. Took a lot of time and two guys up there to fix that chimney after that.
