BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - INSTALLATION
Inverted U
The inverted U has a radiation pattern between that of horizontal dipole and
inverted V. For optimum performance, the radiating elements should be fully
unwound, and should not touch the ground. Suitable for NVIS to medium dis-
tance. Longer distance performance will be enhanced by erecting the antenna
at a height of 10 m or more.
