Introduction

For many years, hams have asked for a surge protector for use with ladder line fed antennas.
Decades ago a spark plugs or arc gaps were used for shunting surges to ground. Now available from
DX Engineering is a modern approach to providing surge protection for ladder line fed antennas.
The DXE-LLSP uses capacitors, resistor and gas discharge tubes on each leg of the ladder line to
offer surge protection capabilities. The DXE-LLSP Ladder Line Surge Protector will sustain
multiple minor surges. As with any surge protector, there is no guarantee that a direct hit from
lightning will be stopped.

Features

 Works with 450 ohm or 300 ohm Ladder Line
 Internal Gas Discharge Tubes, Capacitors and Resistors
 Can withstand multiple minor surges and shunts them to ground
 Standard size NEMA enclosure
 Weep holes for allowing and build up of internal moisture to drain out

WARNING!

INSTALLATION OF ANY ANTENNA NEAR POWER LINES IS DANGEROUS

Warning: Do not locate near overhead power lines or other electric light or power circuits, or

where it can come into contact with such circuits. When installing take extreme care not to come
into contact with such circuits, because they may cause serious injury or death.
