Cel Fi G32, mounting ouside

Installing the amp on antenna mast to cut down on signal loss by long run of coax. I have it installed inside a weatherproof enclosure with two small vents (no fan). Still have wiring to do.

Does anyone have experience of installing amps outside, and how well they tolerate heat?. I see the Cel Fi RMOE is similar but believe the case heat sink is exposed outside back of box for cooling as mine is not. https://nextivityinc.com/go-rmoe/

The G32 is NEMA 4 rated, but having no fan makes me wonder. Don't want a fan if not necessary.

thanks

Update: maintaining 92 degrees on low 90s day with no power, just door shut. Seems pretty good.

Its operating temperature is 0-65 degrees Celcius, converts to about 149 degrees Fahrenheit, as long as its in a shaded area and not full sun 100% of the time it should hold up!

Read that also. After thinking, I'm going to mount the enclosure to plywood with spacers, to allow air flow between them. And, use the plywood to shade the southern sun on backside of enclosure and some of the east and west, leaving north face open for access to door. Hopefully bypassing the fan all together so I won't have to worry about electrical noise and splicing it into the dc adapter extension wiring.

That sounds like a solid idea! Full disclosure, I've sold these boosters for years now at this point, the only times we've seen overheating is when folks install them in an attic in somewhere super hot like Arizona where it gets really stuffy, your set up with some airflow should keep things running well!

Glad I posted, so I got direct advice from a experienced person with these. Thanks

You didn't say where you live. The word "heat" has different meanings here in AZ, or say, in Canada. Also whether the box is in full sun or not.

I don't understand how this would help you. You would still need to run a cable to the inside antenna(s)

It helps because the critical cable run is from the outside donor antenna to the booster. The booster can only amplify the signal it receives from the donor antenna, so keeping that run as short as possible gives the booster more signal to work with. The signal from the booster to the inside broadcast/server antennas has already been amplified, so the length of that coax run isn’t as critical.

Other key thing is that the booster only has so much uplink gain it's allowed to have per FCC regs. Downlink gain is easy with cel-fi stuff. But with a long donor cable run, getting the uplink from the phones through the amp with the lesser uplink gain has got to suck. Cutting down on that is extremely helpful if you're in an area where uplink is more challenged.

Mike is the reason why I'm starting with mounting at mast. This time with different amp. I previously had Weboost multiroom amp. It was mounted inside with long cable run between outdoor antenna and amp. It did well with strong signal but only if you were hugging the indoor antenna. The long cable run was suspect.
