N connector?

jamesbondsv · 07-28-2003

I have this connector on an antenna that I have acquired. I have no idea what kind of connector it is. I am thinking it is an N Male.

looks like a reverse polarity n-male if their is such a thing

jamesbondsv · 07-28-2003

Upon further research, I believe it is a Reverse Polarity BNC or TNC connector.

This website has good photos of all the different types of connectors. http://www.hyperlinktech.com/web/connectors.html

Looks like a TNC, BNC have at least two offsets lugs that snug fit the male and female together with a half to quarter turn. Yours looks like it's threaded.

ex-USAF... Mil loved them BNC types for RF patch panels, but then never gave you enough room to unlock them, scraped many of skin off discounting LRU racks with 200 connectors in the back...<G>

lincomatic · 07-29-2003

maui's right. it's RP-TNC. the threads give it away. TNC's look a bit like mini N-connectors. I got fooled by it at first. Radio Shack sells TNC if you want to go there to compare.

Did that come as part of a linksys antenna kit? Yeah, it IS rp-tnc.

jamesbondsv · 07-30-2003

Now is it a female or male? This is really hard. Why did they have to make so many cable types and do RPs and such? GRR

That is a reverse polarity male.

Part of the reason that the manufacturers make them this way, is that the FCC wants them to use items which are NOT readily available to the consumer. It's sometimes refered to the "Radio Shack rule." If you can get it in Radio Shack, then it's too easy to get, and the FCC doesn't want that.

Here's a good reference:

Okay, I've got the type of connector down. I'm looking for cables or an adapter/connector that will connect to a N adapter (be it male or female).

On the HyperLink site, it lists RP-TNC adapters as RP-TNC-Jack or RP-TNC-Plug. Is this a plug or a jack?

Steve

Thorn · 07-30-2003

Plug = Male
Jack = Female

So it should be a RP-TNC-Plug.

jamesbondsv · 07-30-2003

Now the last thing that confuses me is this table: http://www.hyperlinktech.com/web/con.../adapters.html

If I have the Plug, am I looking to buy an adapter based on what I have or what I want my connector to connect to? I have a Plug, so should I choose RP-TNC-Plug or RP-RNC-Jack?

Do you get what I mean? Do I choose the same as what I have or the opposite?

This is painful on the mind but I'm guessing I will be a little less dumb when I actually buy what I need, receive it, and set it up.

Don't feel bad. This stuff can get very confusing. I order this stuff fairly often, have been dealing with it for years, double check the order before I send it off, and still goof it up every so often.

You have the Plug, so you need the opposite; ie the jack.

If you are going from the antenna above to a N-Female cable, and choosing from that table, then you need the
AXA-NMRTJ

Look at the photo. On the right side you can see the threads that fit into the knurled portion of the antenna plug.

BTW, they don't seem to have a N-Female adapter. If you have a male end on your cable, you're out of luck.

One final note: The connector adapters like this have a about 0.5 to 1dB loss. You might be better off just putting a RP-TNC-Female directly on the cable. Of course, then you have to find the right one for your cable, and a crimp tool is required...

jamesbondsv · 11-14-2003

I bought SOME of the right parts and I find out I now need another part which is ONLY available from HyperLink.

Too bad HyperLink requires a $100 minimum order.

Whilst I agree with this statement, jacks are also usually on the equipment and plugs on the cables - so when the male is on the equipment - as it is in this case - because of the reverse polarity - does that change what it's called?

Thorn · 11-15-2003

"Reverse Polarity Male" or "Reverse Polarity Female" or just RP. Of course, it gets VERY confusing then, as in which part is the "male?"

Sometimes only pictures will help.
