    25 ohm cable...anybody knows where to find this?

I got your e-mail, but I thought I would post anyhow..

25 ohm cable

Precision Tube Co. #CA25047  25+-3 ohms
		   #CA25070  25+-2
		   #CA25125  25+-3
		   #CA27034  27+-3

Uniform Tubes      #UT-70-25  25+-2
(aka Micro Coax)   #UT-141-25 25+-1
		   #UT-300-25 25+-2

As you might guess, one number is the impedance, the other number is the 
cable size in mil (inch/1000), e.g. 25047 is 47 mils, 70-25 is 70 mils.

Precision Tubes 215-699-5801
Micro-coax  215-539-0700

I happen to have both catalogs at my desk, I am sure there are many
other fine companies that make 25 ohm cable.  

Re: semi-rigid cable - Great stuff, I use it all the time.

Re: Two 50-ohm in parallel .. Technically- yes you get 25 ohms (ignoring
    common mode problems) practically, I think it not a good idea. (see
    earlier posting).
