Title: Boxes for HF beacon
Post by: stendec on May 22, 2021, 0358 UTC
What weatherproof enclosures are people using for HF beacons? The planned site is in the high desert, but gets occasional heavy rain from summer thunderstorms. I'm appreciate any suggestions on enclosures and weatherproofing.

Thanks,

you could 3d print and use sealant or find a outdoor box on amazon with the gasket.

I used NEMA boxes for various outdoor projects. They have a seal and are very good at keeping water out. Not cheap but sometimes you can get one on eBay for a decent price.

I've used army surplus ammo boxes.   They come in various sizes and are rugged, inexpensive, usually gasketed, and often painted in a camo color.

I like the ammo can idea and got one with a gasketed lid from my local surplus store.

There's not only room for the beacon and charge controller, but also room to fit a 12v 5AH SLA inside the can. This will keep the battery (and its connections) out of the elements. Now I just need some weatherproof connectors for the solar panel and antenna cables. Or maybe just drill holes in the box and bring the cables in that way -- but might be more difficlult to get a long lasting weatherproof seal that way.

Gland connectors work well to bring wires/cables in and out of the ammo box:

I do like the ammo can idea. If you get a choice surplus military can the gasketing is unbeatable. I've bought cans from this place: https://ammocanman.com/

Im using a 30 cal ammo can to house my 10M QRSS monitor.

One thing I discovered: They can leak .  Mine did somewhere around the handle.

Make sure to check before deployment
