High front-to-back ratio directional antennas for long-range point-to-point links and fixed CPE. This page covers how the class behaves specifically in antenna lightning protection work, and lists the 6 catalog models that fit.
What this class does well
A Yagi gives the best gain per unit of cost and weight of any common directional antenna, and its high front-to-back ratio makes it useful specifically where interference arrives from behind the link. On a fixed path it is hard to beat.
Where it falls down
Narrow bandwidth and a narrow beam. An LPDA covers far more spectrum, and on any mount that moves in wind the narrow beam turns into a fading link.
The range we stock
Across the 6 models in this class the gain runs from 12 to 18 dBi, frequency coverage from 428 to 2483 MHz, and the longest dimension from 465 mm to 1290 mm. Check the size figure early. It decides the mount, and on a shared mast it decides whether the part fits at all.

Specifying one for antenna lightning protection
Mount a surge arrestor at the building entry point, bond the mast and all connector shells to a single-point ground, and keep ground conductors short and straight to minimize inductance. Confirm the connector before ordering: changing the interface later means either an adapter, which adds a mismatch and a failure point, or a re-terminated cable. Standard builds ship with an N-Female interface.
