<strong>KATHREIN</strong> <strong>VHF</strong> antennas <strong>for</strong> special applications:<br />
The “Log.-Per. antenna” from the 75010242 series is<br />
a directional antenna with low wind load and is<br />
especially suitable <strong>for</strong> the specific supply of smaller<br />
towns or along roads. It can be installed with<br />
polarization both vertically and horizontally and can<br />
