It's a 3.5mm F-F connector but not the same grade as the 3.5mm connectors in a typical Agilent cal kit as it uses expanding female contacts rather than the delicate solid centre (with inner petals) as per an Agilent cal kit. So it might not be that much better than an SMA F-F connector, especially as this one is very old and probably quite worn. But I've cleaned it and I'll try it later today. It's really cold and snowy here in the UK and we've been sent home from work early today and told that we don't have to go back until Monday  :)

I'll have an initial look at this connector once my VNA has warmed up.

Now that is dedication!
G0HZU:
It's really cold here because of the gusty wind chill factor and it's hard to keep the house warm. However, I've measured the 3.5mm F-F bullet and the files are below. Note that the room is not that warm even with the test gear on so I don't know if the VNA and Ecal will be stable and OK. Plus this type of measurement really should be done in a proper metrology lab and not with my gear in a spare room in a house.

But here are the results for the 3.5mm F-F left open and with the shorting end cap fitted. The results are fairly good but maybe not as good as I'd expected. I'm off to sit by the fire... the strong winds are sucking the heat out of the house like blowing cold air on a heatsink!

My very budget Kirkby kit - I added the USB drive, male and female through's and Pelican case.

Nice one  :-+

I didn't go for the case or the usb stick. I did get the attenuator and the thru's though.

Mine is still some way away though. I really should use the time to build a case :)

When I say I added the USB drive and Pelican case I was meaning I added it myself. I already had an extra Pelican 1020 sitting here, same as Dave uses.
