1.5″ Diameter 12″ Length Universal Outdoor Adjustable Antenna Mount Pole Bracket to Wall Weather Station Antenna Mast Mounting Pole Clamp Kit

You are going to need another u-bolt with nuts and washers, and maybe another saddle bracket, to attach this to another mast or antenna tripod. This should come with them.This is good for a _directional_ antenna that is installed on the side of a mast or antenna tripod. Don’t use it for a non-directional antenna that you care about, because the metal next to it will distort or attenuate the antenna pattern, and do worse for a transmitting antenna.You should use anti-seize compound on all outdoor mechanical connections, then they will come back apart if disassembled years from now, instead of rusting together. It’s important for stainless steel too, because galling (look that up on Wikipedia) can cause stainless steel fasteners to lock together. Don’t use anti-seize in the antenna connection, it will short it out.This is a 1-foot long 300-series stainless steel (a magnet doesn’t stick to it) tube that looks like a vacuum cleaner wand, but a bit larger and heavier, it’s welded with an internal seam. There’s a saddle bracket that is somewhat thin and also 300-series stainless steel, and a u-bolt which is probably 400-series stainless steel (because a magnet _does_ stick to it). The nuts and bolts also seem to be 400-series, a magnet sticks strongly. 300 series is better for outdoor use, 400 series corrodes more easily than 300 and is generally specified for indoor use, but this is still better than plated non-stainless steel, etc. The L-bracket is aluminum.
