teleco teleplus x2 coax change

The coax on our teleco teleplus x2 antenna is cracked and sheef is fulling apart between roof and antenna. Has any body changed the coax? Have downloaded the installation pdf already.
Any tips would be most welcome

All sorted. It's fairly straitforward to remove the aerial and feed a new coax in.Used RG6 which is thicker and lowloss, therfore needed new F connectors.

We'll done- I guess you are the first to tackle this. In your own words - Any tips would be welcome! . Better still would be a full 
description of what you had to do and any problems you had to overcome.

Nor me, the late Roli did all the ones I have on there......

Working on word doc now. Wish I had taken some Pictures! Will post as a Reply unless I hear differently.

Telco Teleplus Antenna Coax Renewal


You will need: -
Some new coax cable about a metre. Suggest RG6 low loss, it’s a bit thicker than what you are replacing but this is not a problem. 2 F connectors, Stanley Knife, Cutters, Pliers, insulating tape, Screwdrivers, Wipes, dust sheet or equivalent to put on roof. This is an easy job, despite the long list.

2 F connectors – the old ones will not fit new cable. Make sure you get correct ones for your particular cable width, as F connectors come in different widths. If the screw on F connectors slide on the new coax, put one turn of insulting tape around. I found RG6 F connectors require tape on RG6 coax!

1.       Ladder up the side of van that gives best working position. Have a yogurt pot ready to put nuts bolts etc in. Take a picture of existing antenna and its coax position so you can approximate the length of new coax when re-terminating it with new F connector. Same inside the van – Take a picture.
2.       Push antenna up and rotate it Vertically, so you can get to the F connector and 4 screws that hold Antenna on to mast. Suggest putting some cover on roof around antenna. See (Pic A)
3.       Undo F Connector and 4 screws (PIC A). Hold on to Antenna before removing last one. Lay antenna out of the way. Tip - whilst it’s off give it a good clean.
4.       You will see the rounded top of the Mast. It is the top cap of this that needs removing. Rotate Antenna mast back to the Horizontal position. On the top of the Mast are 4 screws/bolts these have captive nuts. Undo them carefully so you don’t lose nuts (PIC A).
5.       Carefully with a screwdriver blade prize the side plates away slightly BE GENTLE (PIC B). This will allow you to lift off the rounded top that the 4 bolts were holding down.
6.       Once off you will see the coax coming up the shaft and make a U-turn back out to the F connector which attached to the antenna. AT THIS POINT CHECK THE POSITION OF THE WINDING GEAR COG AT THE TOP OF THE SHAFT, I SUGGEST YOU TAKE A PICTURE TO MAKE SURE IT’S IN THE RIGHT POSITION BEFORE YOU REASSEMBLE LATER.
7.       Remove F connector.
8.       With the F connector removed you can push the coax out the U-turn hole so that you can remove it from the shaft – DO NOT DO THAT YET, leave it poking up in the air.
9.       Go into your van and disconnect the cable from the Amplifier and any Clips holding it. Remove the F connector and strip a couple of inches so the centre conductor is visible. Bend over the centre conductor and twist on itself forming a loop.
10.   Get your new Coax and strip a couple inches leaving centre conductor. Push the centre conductor of the new through the loop of the old coax and twist it back on itself – Joining old and new cables together
11.   Back on the roof of the van carefully pull old coax up, thus pulling up new coax.
12.   Pull through enough 15 inches or so. Cut off old coax to give a clean end on new coax
13.   Bend over new coax and push through U-turn hole from which in Note 6 above you removed old coax.
14.   Make sure coax at the u-bend point is pushed snuggly down.
15.   At this point before you reassemble – See 6 Above – IS WINDING GEAR IN CORRECT POSITION? Does it need a blob more grease?
16.   See 5 above – reverse procedure. Replace the rounded plate and push side plates back into position. Replace the 4 bolts with captive nuts.
17.   Rotate shaft so antenna would be vertical if fitted. Fit back the antenna and screw up the 4 screws removed in Note 3 above.
18.   Rotate shaft back and lower it into its travelling position so you can approximate length of new coax to terminate new f connector – see picture you took in Note 1 above.
19.   Install new F connector and tighten it up – do not over tighten.
20.   Inside the van refix new coax to old position and put on new F connector.
21.   TEST the signal on TV. Android App - UK Aerial Alignment is excellent

While on this subject:

My Teleco will not adjust to the vertical plane without giving the antenna some manual help on the roof whilst turning the handle inside the van. I took the antenna off hoping to gain access to a gearbox but no joy.

Has anyone accessed/repaired the mechanical bits?

Peter
If you look at step 4 & 5 and remove the domed /round plate you will see the Flat geared shaft that pushes up and rotates another gear to rotate the antenna. It may be slightly misaliged or need some grease or maybye worn down.

Thanks Alan, I cant remember what stopped me at that point, maybe signs of corrosion. I'll have another go when I get a bit of time.

I did suggest another post (sorry can't remember the subject) was added to the Factsheets by Admin but nothing happened. Unless Admin were to add a moderator with authority to add such things, I can't see the Factsheets section expanding.

Thank you SO MUCH, Alan. That is a superb description of huge help to anyone else having to do this repair. It is exactly what this forum is all about.
