VHF 140 To 160 MHz Base Station Antenna With Four Element Yagi, High Gain Directional Wideband Antenna, Anodized Aluminum Build, Static Discharge Protected, DC Ground, Optional Tilt Bracket For Plus Or Minus Twenty Degrees
UPC:
✔️ Single unit, high gain, 50Ω, 200W CW, tilt bracket ±20°
This base station antenna is a directional, wideband four-element Yagi designed for 140-160 MHz. It delivers high gain with a symmetrical radiation pattern in both E and H planes, making it ideal for fixed tower or rooftop installations. Built from anodized aluminium alloy, it has DC-grounding to protect against static and a rear connector for easy access. Optional tilt bracket provides ±20° tilting for precise aiming.
