The KEY to environmental control is ultimately to control humidity.  Water (liquid/vapor) kills electronics.

Now, HOW you control water is the key to longevity.  Basically, you have three factors that impact how well you control the environment:  temperature, pressure, and humidity. If you have all the money in the world, you can produce a standard temp/pressure/humidity in any size volume you want. Money is often the ultimate limiting factor.  Sometimes it is availability of power.... AND money.

For a LOT less than they charge for these communications modules, you can produce an environment for your remote electronics that will insure effective performance and longevity for the components. It costs some money, but if you have the skills, energy, and time, you can DRASTICALLY reduce the amount of money it will take to address the situation.

To the OP:  WHAT ARE YOUR REQUIREMENTS? Volume of artificial environment?  (length, width, height....  a box, a small room, a radio station?)

What equipment do you need to put in the environment....  What are the operating and non-operating specifications for EACH piece?  What is the most restrictive spec for each of the following:  humidity, temperature (high and low), pressure, etc.

Bottom line....  you gotta keep the water away from the electronics.... this involves 1) stopping the air pumping action from outside to inside via thermal/temperature and pressure delta pumping action, and 2) keeping the water vapor that IS inside the environment in a VAPOR state and stopping it from condensing.  There are other conditions and mitigation techniques for each.

But until we know the requirements, we cannot begin to construct a solution.

The Bard cooling units on these things alone will set you back maybe $3500 
each.  One of these would be a great solution.  Larger ones would actually make 
a really nice shack.  But I know, because I used to bid these out and manage 
contractors putting them in, they are definitely not “economical” unless you’re 
quite well heeled. :-)

A little more than a shed but you might consider a pre-fabricated 
communications shelter if you can afford it. You can get them complete with 
power and climate control. Here is an example:
