25mm Pole Mount for HC610 Iridium Antenna

This is a mount that is intended for use with the HC610 Iridium Antenna which I'm using for Iridium ACARS Decoding.

Required things:

• 4x M3x20 Screw
• 2x M2.5x6 Screw
• 4x M3x6 (OD 4.2) Heat Set Inserts

For the heat set inserts I'd probably not use shorter ones, but longer should be fine as there's plenty of depth to the screw hole. I've not tried a different OD as this is what I had to hand so is what I designed around. Again, smaller probably bad, bigger probably fine. These inserts go in the end of the “Main Mount” section in the four holes there. Your smart people, probably doesn't need explaining.

On the underside of the main mount section there are two screw holes for M2.5 screws which are spaced to match the underside of the H610 antenna and hold it in place on the mount - if you use M2.5x6 ones these will fit nicely and not touch anything inside the body of the antenna (as per the manufacturer recommendations of being careful).

It's easier to screw the SMA connection into the base of the antenna before screwing these in.

You may need to or wish to put a little bit of foam or other material around the pole before you tighten it down to help with slipping and/or getting a more snug fit. You can see in the photo showing the end the anti-slip matting that I put in there to give a little extra snugging up to the pole - even if it is scruffy in there it seems to work very well to stop it rotating around on the pole itself or sliding up/down too easy.

So far it's weathered torrential rain, an entire night of ~95km/h wind gusts and more (sideways) rain where it's located so I think the SMA connector hole is recessed enough to protect from water ingress however you may wish to fill the hole with something if you are worried about it. Same goes for the screw holes.

I have this printed in eSUN PLA+ because honestly, I couldn't be bothered with ASA when I was testing it and it doesn't seem to have issues right this second. Longer term, the harsh NZ sun might damage it but it's a fairly quick print to replace it if it's damaged at all (about 1hr 50min) shrug
