سيٽ اپ ۽ تنصيب
Proper installation is crucial for optimal antenna performance. This antenna is designed for NMO mounting.
1. NMO Mount Installation
- Ensure you have a compatible NMO mount (sold separately).
- Install the NMO mount according to its specific instructions on a suitable surface, such as a vehicle roof or a ground plane. A robust ground plane is essential for effective operation.
- Once the NMO mount is secured, screw the Browning BR-180-B antenna onto the mount.
2. Securing and Tuning
- The antenna comes with set screws. Use the provided Allen wrench to snugly tighten all set screws on the antenna. This helps maintain tuning and stability.
- While the antenna is typically pre-tuned, it is recommended to check the Standing Wave Ratio (SWR) across the desired operating bands (144-148 MHz and 430-450 MHz) using an SWR meter.
- If tuning is necessary, carefully loosen the set screw(s) just enough to allow the elements to slide with some friction. Adjust the bottom element for the 2-meter band (144-148 MHz) first, then adjust the top element for the 70-centimeter band (430-450 MHz). After tuning, re-tighten all set screws securely.
