A simple vhf active antenna using a single BFG65 transistor which is a low noise type. The telescopic antenna and the wide band rf amplifier combination is known as an active antenna. The antenna is a ...

Pasternack has introduced a new series of VHF/UHF dipole, collinear and Yagi antennas for various applications, including public safety, land mobile radio, trunking, defence communications and amateur ...

Dual-polarized compact low-profile antenna for airborne synthetic aperture radar (SAR) applications was investigated. The distributed discrete capacitive loads are used to extend bandwidth of ...

A novel wideband circularly polarized (CP) dipole antenna is presented. The proposed antenna is configured with three horizontal layers of an electrical dipole, two parasite Π-strips, and a ground, ...

The rugged outdoor designs of these VHF/UHF antennas ensure high performance in all environmental conditions. The individual folded and straight dipole antennas allow for minimal storage and efficient ...

LPDA The LPDA or log-periodic dipole array antenna, which is mostly used for VHF TV signals, consists of several dipoles arranged in echelon to make a very wideband antenna. "For any frequency ...

In Article Audio PlayerAn antenna with a gain factor of 6 db at a length of 8 feet is adequate for most boats. Larger boats that can support antennas up to 23 feet can make use of higher gain (9 to 10 ...

KP Performance Antennas has released a new series of VHF/UHF dipole, collinear and Yagi antennas for land mobile radio (LMR), public safety, defence communications, trunking and amateur radio ...
