Equipment enclosure

The 6000 series radios are so good remote that I'm considering relocating my radio and amp to a shed which is just 20 feet from my antenna feed point.

While the shed is basically indoors and insulated I have seen quite a few spiders and other bugs in there.

So I'm wondering about an enclosure of some time that would protect the gear somewhat but still let it ventilate.  Obviously it won't be perfectly bug tight as cables need to get in/out. 

Anybody dealing with remote gear and bug prevention, enclosures, etc?  Suggestions and guidance would be appreciated!

Get some slats and window screening and make a cage.

A less expensive cure would be to set off a "bug bomb" whenever the temperature gets above about 50 degrees.

Hey Mark, take a look at the SKB Studio Flyer or a similar cases from other places.  I use one of them for an ARES Go Box.  The nice thing about them is that they are set up for standard 19" racks so the rack adapters for the Flex lets you bolt it right in.  For the Flex, I'd consider cutting holes for ventilation and covering them with something like window screen.  Some silicon or RTV around the cable holes should keep the cooties out of the box.

You can find plenty of NEMA cabinets, both metal and plastic - you can get fans with tight screens and feedthroughs for power, and ethernet - even signal connectors for RS-232 if you need them. - just add a few bulkhead feed-thrus for your RF connectors and its all done.  No spidee's will get into that.

A 5 or 8 thousand dollar radio is worth a few hundred $ in a nice sealed cabinet.

Bud makes this stuff and you can probably even buy it on Amazon.   If it is already inside a shack, you can get the lower-grade boxes that will be cheaper.  They do not have the rain-resistant baffles 

Cheers and have some fun !

Don't know the dimensions of your amp, or potential heat load, but a wall or desk mounted NEMA enclosure with ventilation fans and filters might work.  You could go cheaper or with a different brand, but here is an example. I have no affiliation with these folks, this example is designed for outdoor use and is ventilated.  http://www.rackmountsolutions.net/Great_Lakes_NEMA_12_Type_Wallmount.asp

An indoor possibility: https://www.grainger.com/product/TRIPP-LITE-Wall-Mount-Rack-Enclosure-WP5877592/_/N-qp0/Ntt-nema+12+...

If you can rack mount your gear, you can find a relatively easy solution to keep it sheltered, filtered, even environmentally stabilized - AC/heat/humidity.  Don't forget to measure your gear and cable arrangement carefully to make sure it will fit and figure out how the cabinet will be cooled running legal limit power during a summer  RTTY contest weekend.

I have extensive hilltop and remote station experience. professional microwave sites either use standard open chatsworth 2 pillar racks or the standard closed 42u cabinets.  Spiders and bugs generally avoid the equipment..  but do get into crevices and corners of the racks.  good pest control is always helpful.  There will be bugs.. and possibly wasps. radio will be ok.

Thank you all.  Good advice in all aspects.

I'm always torn on what is the right thing to do.  Currently my gear is almost 150 feet from my antenna feed point.  I've calculated, depending upon frequency like 25 to 35 watt loss over that distance.

Logically I'd like to remote my SPE 1KA to be about 25 feet from the antenna.  I control it over RS-232 anyway and it has a very good tuner in it.

I'd like to keep my Flex near me as I use the amp most of the time.  I don't run a lot of power, I tend to keep my flex running about 5 watts driving the amp which causes it at half power setting to run about 120 watts.   I see this as kind of a way to preserve my Flex finals.

Anyway I'm undecided but figure I need to do something.
