[Elecraft] Coax Switches

[James F. Boehner MD]

I  use the Alpha Delta Series.  They have SO-239 and "N" connector models, two position or four position.  For the price difference, I always get four position.

They are not only well built switches, but they do have surge protection (gas) with a replaceable pill.  Their best feature is the very high isolation they offer:

30 MHz  >60 dB
150 MHz >50 dB
450 MHz 50 dB 

And dB Loss:

30 MHz  0.1 dB
150 MHz 0.15 dB
450 MHz 0.5 dB

So, I wish these could be remotable.  However, they are the best switches I've found for a reasonable price, and I have many of them in my station.

Oh yes, on the outside of my house, I have polyphasers.

I do use a number of Daiwa 2-position coax switches for various 
purposes. Any comments on coax switches?
