- 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).
