Parus-2X tactical military antenna for NATO Band 1
Wideband directional panel antenna covers the frequency band from 225 MHz to 400 MHz.
The original design allows the antenna to be installed not only on a mast but also directly on any surface. To communicate with a satellite or an aerial object, it is enough to simply place the antenna on the ground. The antenna does not contain aluminum parts. Built-in antenna heating is available to prevent icing in severe climate conditions.

Trailer Light Scanner
Trailer light tester YZ-25 makes the job of trailer light testing a lot faster and easier since it powers your trailer's lighting circuits in sequence. You check the operation of all lighting functions in a single walk-around instead of two or three.
Operates lights in sequence. Switching modes: manual or automatic with adjustable duration.
The tester is custom-made. The case and battery that are most convenient for the customer's conditions are selected and agreed upon with the customer. For example, it is possible to use from the power tools available in the customer's workshop.
Price: 410 EUR excluding case and battery
