I have had to move my Glomex RA106 antenna but cannot find the correct cutting length of the inner conductor, the inner insulating sheath and the outer braided screen. This antenna has crappy solderless connection which do not inspire confidence.

Can anyone help me with the cutting dimensions,

Thanks
 
Hi John

Just about to do a similar job.


Place outer nut on cable.

The outer sheath is cut 20 mm from the end and the braid cut to 16 mm long, the braid is then folded back on itself.

The inner 'nut' screws onto the braid.

The inner insulation is cut 8 mm from the end of the cable, the conducor is then folded back on to itself.

There needs to be a gap of 6 mm between the inner 'nut' and the inner conductor that was folded back on itself.


I hope this helps, any problems please contact,

Regards Alan

Thank you for the cutting details and a very warm welcome to PBO.

Hello Malpasman,
I saw this advice recently and need to reconnect my vhf cable at the deck after a pretty unsatisfactory (one sided) conversation with a guardship yesterday suggested it had been displaced again.I'm hoping that this time I can make it as secure as a fitting without a mechanical clamp will allow.
Is this the arrangement you are suggesting - the view after preparation ?
 
Hi bluerm166

Just to be clear the dimensions and fitting instructions are for the solderless connection fitted to the Glomex RA 106 antenna. The coax used was the RG 58 supplied with the antenna.

Are you planning to use the same connection at deck level?

I would use a solder connection [PL 259] if possible, at deck level, unfortunatly you do not have the choice at the antenna end.

With regards to your drawing, it depends on how sharp you bend the inner conductor back on itself wether you have 4 or 6mm gap between it and the outer braid. I use 6mm gap and it works for me.

If I can be of any further help please contact

Regards Alan

I was looking at the arithmetic in the pic of 20 - 8 -8 = 4 which would appear corect but in practice the gap will be greater due to the wire lost in the bend so I think the 6 mm is correct.
 
vhf coaxial into GLOMEX

Thank you for your comment.
As I need to remake my connection before venturing out again ( the guardship lies between the mooring and the open sea and I don't want to appear rude twice more) I contacted GLOMEX at lunchtime by email and had a reply within hours with a pdf attached.
I did ask for the best method so I would like to follow it.
Only trouble is I have no means of soldering when afloat but the inner conductor has always looked a curious fit into the hollow spigot.
The pdf consists of a photo sequence and is annoyingly larger than the upload allowance.So these are lower quality jpeg conversions.
I could send the original pdf to anyone who pm's me their email address.

Those pictures are of a PL259, not the Glomex solderless connector. The solderless connection at their antennas is different - the item in the picture is a PL259 'screw-in' version, which just means the braid screws into the body of the PL259 rather than being soldered in place or being trapped there by an adapter sleeve. You'd use this at the radio end.
The solderless antenna connector is something far more mysterious!
 
Coaxial to Glomex

First of all thank you to Malpasman who has pointed out by PM that the details he provided were for the aerial itself and not for the connector that I have.
Also to Salty John who makes the same point.
All I can say is that I have inherited an RA105 gold plated thro deck,with a PL259,plus a rubber shroud and it's a pain in the a***.
But I now know more than I did,thanks to the forum and Mr.Alessandro Bambi and I won't deflate the inflatable on top of the connection ever again.
 
Hi John,

the connection to the antenna end isn't as positive as I'd like, and too easily pulls out - would be no fun at the top of the mast, but I've been lucky for two seasons now.
