Thread-topic: [CRTech] Dehydrator?

The low pressure is for large waveguides where anything higher than about 1 psi ruins the waveguide tuning.  I once worked at a TV station in San Francisco where a malfunctioning pressure regulator put about 8 psi on the waveguide to the antenna on Mt. Sutro.  Every section of that waveguide had to be re-tuned.

It likely has the required volume but the pressure seems low for a typical FM installation.  I'm used to seeing 3-5 psi rather than less than .5 that this unit runs at.

About 200 feet of 3 inch line.


I thought the specs on the replacement unit may be weak for the large system.

What is the length of the coax?

SCMS says the inexpensive Commscope 40525B dehydrator is no longer available and replaced by the HR150.


Is the HR150 what we need for a 6 bay broadcast antenna with 3 inch coax?
