I picked up a Rocketdish RocketM2 radio for WiFi reception and tried to
mount it on an old Dish-TV antenna arm.

The problem is it's about six inches too short (see picture above).

I had planned on bolting this to the wood boards framing the edge of a
tile roof (without going on the roof itself).

Advice sought:
a) Would you just extend the mast with a pipe?
b) Would you buy a new mast (from where)?
c) Is there another trick I can't think of?

I'm hoping a clever idea will pop out of this.

Otherwise, I'll just buy a new antenna arm and make sure it's longer
somehow!



On my own kit, I actually used a short piece of schedule 40 PVC, slipped
over the end and bolted through both pipes with washers. So far it has
served me well for 8yrs and held up through two hurricanes, but I have
no idea what your own localized weather situation is. Can't remember
anymore what size I used, believe it was 1 1/4", but you should be able
to figure it out.

Eventually, exposure to sun and elements will take a toll on exposed
PVC, but may work until you can come up with something better.

EMT would work just as well, last forever, but if ice and snow is an
issue, you should probably cap the end: you would not believe what
freezing can do to to metal pipe of any sort.

Worst case, purchase a length of similar sized EMT from almost any big
box or hardware store and either fashion a temporary pipe bending jig,
very simple, or find someone with an EMT bender and cut to length.
