Building Rugged RF For Outdoor Installations

[Scott Elliott]

I'm looking for tutorials or other guidelines to build up my outdoor RF box that can be left outdoors for an extended time.   I'm looking for some engineering informed practical guidance to the craft of moving from a bunch of strung together bench components to a solid and trustworthy outdoor prototype I can set and forget.  I'm finding a lot of "here's what I built" types of videos, but not a lot of prescriptive instructions.  What little I am finding is old HAM wisdom for way down in HF.  

I have a ton of nitnoid questions that I would hate to inundate this list, such as glands vs bulkhead, mounting hard connected components that have different height, mounting to heat spreaders, etc.  I guess I'm trying to short circuit doing detailed engineering for every bend radius, etc, when anyone skilled in the field know that you just do X or Y.  

Thanks,

-scott

Hi Scott,

I would say inundated this list with them! Your questions are relevant to many of us and equally the answers from the experts here will also help a lot of us, now and in future.

Hi Scott, 

Whit in Alaska has so much equipment, well documented; what's his website? I can't remember but someone else will. 

Good luck! Wende

Wende,

Found Whit's amazing site https://reeve.com/RadioScience/Radio%20Astronomy%20Publications/Articles_Papers.htm#Shop_Practice Thanks.

Hey Scott, 

You're very welcome. I hope you will send us pictures and documentation when you are finished.

Wende,

I bet you are referring to:

https://reeve.com/

Whit’s publications within the above site are listed here:

https://reeve.com/RadioScience/Radio%20Astronomy%20Publications/Articles_Papers.htm

Were you thinking of any specific publications that reveal practical network assembly planning, and weather hardening?

Cheers!

Art

Hi Art, 

Not really (although Scott seems happy for now). I just hoped that was a good place to start. Whit has done so much, so well - I would have moved there and followed him around like a disciple if it wasn't for the extreme cold, and the mosquitos, and the high murder rate for women.

Hi Scott,

What  exactly  is your   objective?

Do  you want  to design  your  own  RF  PCB?

Do  you want  to buy  existing modules  and put them into a weather  proof  box?

A few  years ago   I  started with this  weather proof  box  and it has  worked very well...    https://www.amazon.com/dp/B0B87WGR6L?th=1

I  designed  some  pcb's using   Kicad  and  JCBPCB to make  and stuff  the pcb.  I found it is  cheaper  to buy  existing modules.

If  you are interested in 21 cm Hydrogen Line  a  good place to start is with  SARA's Scope in Box   or  The  Discovery Dish with  Discovery LNA.

A  good  rule to follow is place  the Now Noise  Amplifier  as close as  possible  to  your  antenna feed and all digital electronics  as  far away  as possible  from your  antenna.

It is  difficult  to answer  your  questions  without  knowing  more specifics.

Correction   JLCPCB   does a  good job of making your  pcb   from Gerber  files  you  export from  KiCAD 

JLCPCB      https://jlcpcb.com/

KiCAD         https://www.kicad.org/

If  you are  looking  to  design  your  own  board,   for  Hydrogen Line,  here are the docs for the  Quorvo  chip   used in  Discovery  Dish  Feed   LNA...

https://www.qorvo.com/products/p/QPL9547#documents

Much  easier  and  cheaper to  buy  the  Discovery Dish  Feed    from  Crowd  Supply.

Your   antenna  and front end are the  most  important.....    

What is  it that  you  want  to do?
