Question

Making a new Reverse SMA connector (WiFi antenna repair)

Asked by: sconnell

Hello folks... I don't understand why there isn't a proper wireless forum. Anyhow,  I hope the right people read this.

I have a Netgear WG302 with external antennas attached via a reverse SMA connector.

The connector just broke tonight and as of tomorrow WiFi will be a problem for a few people (fortunately not a big deal).

The cable is labeled as: Harbour Industries HPF195-FR CATVR 75C 19 AWG

My questions:

1. What tool(s) (e.g. crimp tool for this type of connector) do I require to replace the broken connector on this cable?
2. What parts do I require (crimp connector, Reverse SMA connector, heat shrink tubing - anything else)?
3. Where do I find these parts (in Canada - preferred)?
 
Thank you,
Shawn

1.
19 AWG means 0.912 mm. That's the conductor diameter, but it does not concern you when it comes to the connector needed.
What you have to know is the diameter of the cable, wich is standardized, but unfortunately I can't find what kind of cable is that cable of yours. I can only guess (a presumption only) that the "195" number from your code reffers to a LMR195 cable, wich is a standard - and that is 4.95mm outer diameter - 7806A from Belden.
In this case you'll need the connector for an RG58 cable and a crimping tool for the same RG58 standard.

2. you'll need the connector and the termo-reactant rubber tube (optional)

3.  I can't help you here, I'm on the other side of the world :)

" the above link gives all you need."

@Mikal
This is such a non-professional statement. YOU can't decide what the asker wants, and state that is all he needs. Besides that , it is also rude to other experts that are actually taking some time to explain something, instead of droping a link found on google with a 0.1x seconds search.
How would it be if I'll follow your example , decide that all the asker needs is MY post and besides that, I'll make use of my privileges as a PE and force accept my own answer?

Such attitude from you and others were the main things that influenced me in my decision to retire from EE. This is my first Q in EE in looong time, and here you are, the same - unaltered.  

Please revise your attitude, this time I'm in a mood to answer Qs.

Hello,

Thank you for the info.  

Mikal613: Thank you for the link... At least I can email them to provide the parts required.

Kronostm: Thank you for the additional details. Actually, I am familiar with many cables (except for this type). I still don't know what impedance or capacitance values are required.... but the link Mikal613 provided should be good enough.

Best regards
