Re: [amsat-bb] DC to Preamp with ICE Arrestor

[Phil - KB9CRY <kb9cry@xxxxxxxxx>]

You can order the unit with the DC pass capability; it's just a special 
order from ICE.  I have one and it works fine.  The left side connector 
goes to the radio and the right side connector goes to the antenna.  But 
you may be mistaken that this unit is also a bias tee, meaning, a unit 
that allows one to hook up a dc voltage source to power a remote unit. 
 My belief is that it is not a bias tee, just an arrestor that allows DC 
to pass through.  Go to Down East Microwave for bias tees, or make one 
yourself; they're quite easy to construct and use simple components.
