SDS200 in attic

[MilAirNJ]

Just set my SDS200 up in the attic. (Had to move my radio shack to the basement so our kids can have rooms lol) The long LMR400 run to the basement just wasn’t cutting it. I now have the 200 running almost directly to a yagi.

I figured since these run in vehicles during the hot and cold, this should not be a problem. Has anyone had any luck with running one in the attic with the heat and cold?

I have it running to proscan VIA a wireless bridge.

Semiconductors do not like heat or extreme cold. The Operating temperatures list on page 46 of the SDS200 manual list +14F to +104F degrees. Electronics should only be installed in a climate-controlled environment. You mentioned vehicles, The interior of a vehicle is considered a climate-controlled area, it is heated in winter and cooled in the summer. I have Lived in Texas, Nevada, Utah and Colorado and will I tell you I have had scanners and GPS fail to operate when parked in parking lot with no shade on a hot summer day until they cooled down especially if they were left in direct sunlight. Will your SDS work in the attic, yes for a while but why risk it.

400 is good cable,how long is the run. Why do you need a yagi, it it for distant systems

Temperature changes will put a strain on electronics and wear it out much quicker. There's a reason to why there are AC equipment installed to keep a steady and even temperature in computer server rooms and in the room where radio equipment are held at a site.

If the antenna are only used for receive you can put an amplifier at the antenna and use cheap thin easy to route RG6 coax, that have an attenuation of 6dB/100ft @900mhz.

An accelerated temperature life cycle test, or thermal cycling test, is a method used to evaluate a product's reliability and durability by exposing it to repeated, rapid shifts between extreme high and low temperatures. The goal is to simulate the effects of real-world temperature variations and uncover potential fatigue-related failures, such as cracking or delamination, in a shorter timeframe than normal usage would allow. This accelerates the aging process, providing data to predict a product's normal operational lifespan and identify design weaknesses.

Thank you everyone for the replies. I am well aware of the downside to doing this and will keep everyone updated on how long the scanner will continue to operate up there

"so our kids can have rooms"

I'll take a wild guess and say about 18 yrs it will be up there.
