FAQ
Does the antenna require SWR tuning?
The antenna is pre-set at the factory for amateur radio bands. However, fine adjustment is possible via the clamping screws if the installation environment requires it.
Can it be used on a magnetic base?
Yes, its ground plane-free (radialless) design makes it particularly effective on magnetic bases of sufficient diameter (minimum 12cm recommended for mechanical stability).
Is the whip removable?
Yes, the whip can be removed from its base for transport or to prevent theft during prolonged parking.
Why choose the Komunica PWR-SG-7500?
- Excellent gain/size ratio: With only 1m05, it competes with much bulkier antennas in terms of reception.
- Komunica reliability: A brand recognized for the durability of its RF components and the quality of its finishes.
- Extreme versatility: Whether for local traffic or via relay, its omnidirectional directivity is optimized for mobile use.
- Sleek design: Its chrome finish and aerodynamic profile blend perfectly with any type of vehicle.
