[Boatanchors] RG-174/U and BNC connectors?

Eugene: Be sure to check the patch panel if it uses 75 Ohm or 50 Ohm BNC's.

Hi all, few questions on connectors and cable.

I am setting up my shack and hope to use some short patch cables between
devices using a 32 port bnc patch panel I acquired.

For example, I can patch the output of a radio to one of two TUs or the AF
in on my PC sound card.  

Question 1. is, for HF work, is it a big problem if I happen to patch some
antenna signal using rg59 if everything else is 50 ohm? Would it make any
more/less difference for Tx (100W input transmitter) rather than Rx?

Question 2. is, for video, is it ok to use an rg 58 50 ohm for a short run?
I have a vhf/uhf receiver that has video out, and the length from the Rx to
the Video monitor is perfect for a 50 ohm patch cable I have lying around

Question 3. I would like to make up some of my own patch cables with bnc and
some rg-174/u I acquired.  I am looking to find some cheap bnc connectors
(either solder or crimp) and came across this. Can anyone recommend anything
better/cheaper?

looks like the last is the cheapest at 1.29 each. Figuring I want 20 of 'em.

thanks for any advice
