The SA LP20SD-14 is a high-power broadband log-periodic antenna designed for precision EMC testing, RF immunity evaluations, and industrial applications requiring reliable and repeatable field generation across the 20 MHz – 100 MHz frequency range.
This rugged antenna delivers +6.5 dBi nominal gain with a power handling capacity up to 10 kW CW, making it ideally suited for demanding test environments and high-field strength applications. The dual-polarized design features a built-in 0–15° tilt interface that enables manual selection between vertical and horizontal polarization, providing complete flexibility for test setups and compliance testing standards.
Engineered with a 50-ohm unbalanced feed, the SA LP20SD-14 maintains a maximum VSWR of 2.5:1 and offers a wide beam coverage—approximately 65° (E-plane) and 105° (elevation)—for uniform field distribution in test chambers or open-area sites.
The antenna’s all-aluminum construction with a gold Alodine finish ensures exceptional corrosion resistance and mechanical strength. It mounts securely to the SA LP Stand-Heavy fixture for stable operation and precise alignment.
