RF Connectors Assortment

I spent a good 20 minutes the other day, trying to make an antenna fit a Wireless LAN (WLAN) card. It just wouldn't snap on, and finally, I realized the antenna had a U.FL plug, whereas the WLAN card had a MHF 4 socket : )

I'd never heard of MHF 4 before, but it seems to be very popular in the laptop computer world. Anyway, while I was at it trying to visually compare the connectors, I took this photo - perhaps useful for identifying connectors in the future : )

The photo is missing connectors, especially some common ones like N connector, and the PL-259 (popular in ham radio equipment).

BNC of course is very popular, as is SMA. I really like SMB, it's like a hassle-free version of SMA, but unfortunately, it is not as popular on equipment.

(Click photo to enlarge):

EDIT:

Decided to re-take the photo and add N and TNC. Also added a PL-259.

Hi Cris,

Good point, I don't have many 75 ohm connectors but found a 75 ohm BNC socket for this photo comparison with 50 ohm:

Tada, GR874 to N pn 874-QNP

Believe it or not I still use them on some equipment, but I use the adapter to 50ohm BNC

Thanks, phoenixcomm. This part may come in handy on a project I'm working on.

I could really do with getting hold of a couple of these GR784-TNC Coax 50 ohms. Does anybody know if I can get my hands on them in the UK?

I got some SMA components recently. To check which ones I can use best for measurements. A few T-adapters, BNC to SMA adapters, a bit of 50 Ohm cable, 50 Ohm terminators.

Nice assortment! I prefer SMA antennas and recently got some u.FL to SMA cables.. but I need to improve using those, I find it very difficult to keep the u.FL connector aligned while pushing until it snaps in. I have tried using round bar, since then I can keep that vertical, I just about manage. Might try to make a tool one day, or buy something (don't want to spend a lot since I don't plug so many in!).

I have a trick. The first time I tried one, it embedded itself under the skin of my thumb .

But if you align it over the connector by holding the coax cable between thumb and index finger, just in the right position (and with your tongue in the right angle), you can press it down and it snaps in.
