Hi all,

I am currently on a archeological surveying excursion in the UAE. One of my Promark3 Coax external antenna cable (702058) isn't working any more, the other one connects the GPS devices and the antennas without any problems. The local supplier of ashtech products told me it would take two weeks to get a replacement, thats of course to long. Has anyone discovered this problem before? Or has anyone an idea how I can repair or improvise?

The cable itself shows no visible damages. The cable seems not broken, the fittings seems ok.

Thanks for any help in advance,

i'll look into this a bit more when i get home, but you might like to run a search for the Promark3 on the network and connect with other surveyors who use this instrument daily...someone is bound to sort this issue out for you..good luck...i'll try to be back to this asap..

Hello. That should be a cable problem because if the other cable works fine must be a problem in the cable. Try, when the cable is connected, to move a little bit the connectors to see if that can be a bad contact and try to see where the problem is. The cable can be very good outside, but if inside has someting broken it wont work.

Thanks for the fast replies. I removed the slipcovers from the connectors - looks also fine to me. I put some contact spray on them and will test again - I'll keep you posted.
:( it didn't work

Hi Michael,

thanks for looking for the cable. Yes it is the one I need. I tried everything to get one here, but the local distributers told me it would take them at least 2 weeks to get one here. In the meantime I could borrow another system, even though I don't like to mix data of different systems. In a few days I'll be on my way to Tanzania, where a colleague of mine promised me to bring a cable he just organized today in Germany.

Thanks  - also to the others who replied on my post!

Hello Guy,

One day I was working and atenna cable stopped working. It was loose inside the protective 

plastic. You can look at this. See the photos!

Hi Savio,

yeah I had removed the protection completely - and I have done it again after your post. The connectors seems ok to me, I adjusted them a little bit and put it all together again - but still nothing.

Thanks for your post and the pics, I appreciate it really.


Hi Felix,

We are cables manufacturer for GPS devices. May I help you, Or is your problem already solved ?

I can send one today from France. Is it useful ?

Hi Arnaud,

thanks for replying. This offer would have been great a week ago, but our stay in the UAE is finished tomorrow and my colleague organized another cable already yesterday in Germany and will bring it to the next survey.

Next time something is wrong with a cable I will send a message directly to you.



Hi Felix,

Sorry to be late. I just found your message on monday. As I was not yet a member of this forum I was not able to answer.

If you have any need for help or cables, do not hesitate to contact me on [email protected]


Hi Felix,

I am glad the issue is solved already, and i am sure you could get a new cable from us earlier then 2 weeks, contact me next time you need one or any other piece of surveying equipment, i'd be happy to assist "QUICKLY"... :)
