Advice for external/outdoor aerial extension - Business Improvement
**Hardware version not know right now**
I am looking for advise regarding achieving a better 4g connection for use within the business I work for.
Currently we extend the 2 aerials to be outside of the machine, as it was manufactured with original small antenna placed within our electrical cabinet so wasn't achieving any higher than 25% signal strength, 0% in most customers factories.
We now have numerous customers where the machines will be placed in more difficult situations such as freezer rooms. Signal strength is poor on every device within these places so I need a way to extend the aerials to be outdoors, or atleast through insulation until signal can be achieved.
What is the maximum advised length of cable for the aerial?
Do people know of any devices which could help in this situation?
Any advise would be great.
