The box can be supplemented with a pressure valve at an additional cost.
Function of the pressure valve - if the instrument box is exposed to temperature changes - e.g. the difference between day and night temperatures or if heat is generated in the box during operation and the box cools down after operation - pressure changes and condensation of water vapour occur in the sealed box.
In some cases, a vacuum may even be created, which can cause dust and moisture to enter.
Installing a pressure equalizing valve is a very simple way to provide ventilation while preventing vapor condensation and dust from entering the enclosure.
If you are interested in installing a pressure valve, add the valve offered in the Accessories category to your cart. The extra charge is the price of the valve.

Attach the coaxial cable to the balun so that it does not hang by its own weight on the connector.
