Antenna for UHF VHF Links

147



Meter loopThe Antenna is more or less Omni Directional and horizontally polarized.It presents a high takeoff angle and is intended for use in the 144.200mhz area

New Helix Antenna DesignGain: 15.9 dBci approximately 1 to 1.5 dB better than the standard Helix antennas I have modeled, pattern: First Side lobes at 36 degrees down 14 dB Average of all remaining sidelobes <25 dB, bandwidth: <0.2 dB variability from 432 to 438 Mhz 50 Ohm Match at <1.2 VSWR from 432 to 438 Mhz

Omni-Gain Vertical Collinear for VHF and UHFAn omnidirectional collinear, is capable of surviving harsh environments. It's a good choice for repeater installations and can be top, or side mounted to the tower

Origine et principe de l'antenne directiveSimplicity in terms of its performance, equivalence with a Yagi antenna, optimally sized, three elements with wide spaced, or four elements with close spaced

7dB VHF Collinear Antenna
This project is about a cheap way of building a colinear antenna for VHF 145MHz, and having about 10dB
