[R-390] R-390A Antenna matching, 26Z5W, 3TF7, 0A2 replacements available? Recommendations?

[James Anderson]

Do you know if Sigmaperts replacement as follows are still available?


  1.  BNC 50 ohm unbalanced to Twinax 125 ohm balanced antenna adapter for the R-390A
  2.  26Z5W replacement
  3.  3TF7 replacement
  4.  0A2 replacement

I am looking to update my R-390A and from a couple of recommendation you made of them I would like to buy them.
If not available do you have suggestions for substitutes?

Thanks for your help,
