How mount accessories on radar mount pole

[Yeoman_24]

I Jane a 2 meter high stainless steel radar mount pole with a Garmin GMR18 proudly atop fixed to my transom. . Seems daft to have rail mounted Navtex aerial or tv aerial so what is the best way to use this stainless steel beast for more than just mounting a radar?

I have a similar post with a TV aerial on the top (it was there when I bought the boat). I have been trying to work out how to mount an AIS antenna up there too. The TV antenna is mounted on an adjustable mount, bolted to a flat plate at the top. I have been looking at using a piece of flat s/steel strip mounted on the same fixing as the TV antenna and a flat mount antenna mount for the AIS on the end of it.

I did it like this, aerials for GPS, AIS and DAB radio.

I like it. Just the sort of thing I want to do. What parts did you use for it?

25mm sa pipe bendt to shape.
T is made with two connectors from Nawa turned 90 degrees to each other.

I found adapter with threads in one end fitting over the pipe in the other end for the gps antenna.
The pipe is fixed to underside of platform using pipe clamps, to prevent it from turning upside down there is a anti rotation bolt going through pipe into a threaded hole in platform

The T is made using two of these rotated at 90 degrees angle.

These used to attach to platform

This for the antenna with thread attachment
