Discone Antenna Calculator


A discone antenna is a version of a biconical antenna in which one of the cones is replaced by a disc. It is usually mounted vertically, with the disc at the top and the cone beneath.Omnidirectional, vertically polarized and with gain similar to a dipole, it is exceptionally wideband, offering a frequency range ratio of up to approximately 10:1. The radiation pattern in the vertical plane is quite narrow, making its sensitivity highest in the direction of the horizon and rather less for signals coming from relatively close by

Antenna for UHF VHF Links

153



1 Element 50 Ohm Yagi
The dipole is mounted vertically 250mm in front of a metal support, the gain is 2,65dBd at 5,5dB F/B

A centre-fed coaxial dipole for 4m
The feed is essentially a delta-match, which makes use of the intrinsic capacitance of the two co-axial stubs

Antena Jpole - TOPFKREIS 435mhz
This antenna is nothing more than the coaxial version of the Jpole antenna. It consists of a half-wave radiant element, the electrical equivalent of the half-wave dipole

Antena yagi 2 metros
An antenna for vhf 2 meters, and a simple three-element yagi with range adjustment worked well for me

2 Meter Halo Antenna by Mike Fedler
Wanted an antenna that was simple, horizontally polarized and omni directional
