Power Supply on CM7777

I am helping a friend with an antenna install and have a question about the CM7777 power supply.

In the directions it says to keep it free and clear of heat producing devices (Amplifiers, TV's, etc). At some points in the directions it seems to indicated that it is to make sure you don't block the ventilation of the device you are setting it close to (the amplifier, TV, etc).

On the other had it seems to say that it (the powersupply itself) needs proper ventilation.

My friend has a chimney mounted antenna. He has a satellite dish, and a multi-switch. We need to put the powersupply before the multiswitch (it is a 5X8 switch). His Multi-switch is in his attic. There is power up in the attic (for the light, and his powered multi-switch). Nowhere on the CM7777 docs does it give information on operating temps. Does anyone have a good on if it is okay to put the powersupply in the attic?! It would not work unless it is before the multi-switch, and this is the only place that we can put it unless we route some coax out of the attic to power the amplifier, and then run the coax back into the attic to hit the multi-switch input for the antenna.

So it is like this:

Antenna -- Amplifier -- Attic -- Powersupply -- Multiswitch -- diplexer -- TV/SAT

We could go like this if needed, but want some feedback:

Antenna -- Amplifier -- Attic -- coax to closet inside -- powersupply -- coax back to attic -- multiswitch.

Found a solution....the MS has a 18VDC output...with the use of a DC-Passing splitter I am able to get power to the amplifier.

I connected one of the splitter outputs to the DC Output of the MS (which sends 18volts to the antenna amp, exactly what it needs). Connected the amplifier/antenna to the input of the splitter. The second output of the splitter runs into the MS Antenna input.

Thanks to the diodes in the splitter, the power is not back-feeding to the second output.

So..anyone need a Channel Master Powersupply

I sent you a Paypal payment for the CM power supply 3 weeks ago. When do you plan to ship it? You've told me twice you would provide tracking numbers. I've never received those either. I've sent you two private messages that you've still never bothered to read. What's up??
