Specification:
Item Type: Coaxial Lighting Arrestor
Material: Iron
Model: BL-2000
Connector: PL259 Female to PL259 Female
Frequency Range: DC~1000MHz
Voltage VSWR: ≤ 1.1
Peak Power: 400W
Impedance: 50 Ohm
Features:
1. Comprehensive Protection: Absorbs and grounds lighting surges from antennas on top of buildings, providing complete protection for transceivers, receivers, etc.
2. Safety Guarantee: Designed with high safety in mind, the built in inflatable lighting arrester element discharges and grounds the surge when the surge voltage exceeds a specified level.
3. Convenient and Practical: Surge discharge and recovery action can be repeated as needed. If the lighting arrester components are damaged, they can be easily replaced with new components.
4. Superior Performance: The coaxial structure of the lighting surge protector ensures excellent high frequency characteristics, wide bandwidth, low loss and VSWR.
5. Easy Installation: The coaxial lighting surge arrester adopts 1/4 wavelength short circuit principle, good lighting protection. Simple structure, sturdy and easy to install.
Seems robust and well constructed, with a noticeable weight. I will test it in the country house during holidays. Will see if it matches specifications, i.e. does not affect VSWR nor reduces TX power. About the effectiveness of the protection, better not to have near lightning sparks to check it
