as Doug stated it is a hex screw (otherwise known as an allen key)...

Thanks. It seems like someone has burred the edges so will have to take remedial action.
Does amyone know the coax connector at all ?

Can you be a bit more specific? What do you want to know about the connector?

I haven't seen one. It appears to be inside the assembly and I can't get the grub screw off at the moment, although the coax just pulled out with a centre connector pin.
What kind of connector should sit on the end of the coax? PL259?

No, it is a connector peculiar to that type of antenna.
The PL259 will be on the radio end of the co-ax, but the other end is much larger.

When you eventually get the grub screw out, the top section (white bit) of the antenna unscrews off the base. This undoes the connector which is in the base.

The connector is pretty much the same as the base of the AE409L.

If you have the co-ax right out of the antenna base, it might be stuffed, I don't think it is supposed to come right out.

I used to know the coax connector, but he owed me money so I don't talk to him anymore :-)

Make sure that the hex socket in the grub screw isn't full of hardened mud.
If you are trying to disconnect the coax at the aerial end, I am pretty sure that it is a permanent connection.

Hi Footy

Seeing you are near the West Burleigh area, try Auto Barn in
West Burleigh road, if you are chasing C B aerial parts, they keep
a range of bits & pieces, also if you buy from there they will fit it
at a reasonable price re the cable joints ect and test it, some times
they will do it free.

Cheers
Daza

Many thanks to all. Yes, Auto Bahn might be the go as Jan works with the owners wife. Will see how it all goes...it's a flavour for a friend.

G'day Footy,

Trust all good with you?

Those aerials have the PL-259 built into the base of the whip, and an SO-239 (???) is fitted into the top of the spring base, down below where that grub screw is.

Been a lot of thought go into the designing of these, with both co-ax connectors protected from damage, in the whip & spring base. There are at least 6 different whip configurations that one can use, depending on requirements.

I went off them a few years ago, because the whips would go out of tune in a short time, even after trying 2 or 3 different ones. Might have been our road into Winton......certainly not my driving LOL

Regards,
Bob.

Hi Bob, hope all is well your way also.
All would have been good if I hadn't heard from a certain mate of mine who wanted stuff ripped out of one vehicle and installed into the "new" hilux in 40+C. And of course he's off to Winton tomorrow...rush job. I
normally don't do installs, never seen a hands free kit before nor an irridium in car kit. Out they came, plus the two Icom Pro's.
The coax in the UHF aerials just slipped out of the springs...is that normal? I don't imagine it is.
Ended up drilling one out and as you say, the so239 connection isn't easily got at. It's a diabolical design to say the least, but they are so exe that I couldnt just throw em, so we dodge'd em up a bit.
They're not going anywhere.
Does the lot now work ? Don't know, don't care. Too stuffed to worry that the guy rang me and said hey I can only get scan...said Priority chan.......
I downloaded the manual for him and he wanted me to read it and find out what was wrong!
I rekkon I've done my bit over the last couple of days.

LOL Sounds like we've unknowingly passed each other on that road before, Footy.

Don't think the co-ax should slip out of the spring, not unless it was damaged.

Sounds like a couple of hard days, might change the subject, so you're not reminded of it.

Regards,
Bob.

Feel slightly better this morning:)
You'd know me when you passed me. I'm the grey haired old coot with the baseball cap on doing 80K/h. I don't know that road all that well, and am always on the lookout for animals and road trains.
Usually have the big Codan aerial and an exploroz sticker on the back of the 80.
