The zeppelin antenna for 50 Mhz - A end fed antenna used on the big zeppelin airships (thus the name ZEPPELIN antenna) of the 1930's where the wire trailed behind the dirigible.

4Z5NY Antenn calculators - The formulas for a dipole and vertical, j-pole, double square, Yagi and EH antenna calculators

Double Bazooka Dipole - The Double Bazooka Dipole is a very efficient antenna which is very quiet,and does not require the use of a balun

Double Bazooka Antenna performance - The Double Bazooka Dipole is a half wave dipole with an attempt at compensation of the reactance change that occurs around resonance for a half wave dipole.

An Improved Multiband Trap Dipole Antenna - This improved multiband trap dipole introduces a new trap design and a change in trap location. The antenna features double-coaxial-cable-wound traps having lower reactance and a higher quality factor (Q) than earlier coax-cable traps by W8NX

Multidipole Antenna - This antenna is a group o dipoles, is a multiband and each dipole works on single band.

Feeding an End-Fed Antenna  ^pop - End-Fed antennas are NOT balanced systems; but neither are verticals, ground planes, discones, windoms, zepps, Marconis, half-slopers, et al. Additionally, the low-impedance antenna port of your transmitter/receiver is not balanced.

W0OXB All-band Zep Antenna - W0OXB All-band Centerfed Zep Antenna 160m-6m

WARC 24 18 - 3 element Yagi Antenna - An old project by I1VCF for a 3 element yagi antenna originally designed for 10/15/20 and extended to 24 and 18 Mhz in Italian

Bicone antenna - This antenna is a simple double bowtie biconical dipole design. It was designed as a broadband scanner antenna resonant on the 2 meter ham band.

Stealth Zepp Antenna - Photo album of a stealth zepp antenna

Patch antenna for APT - The patch, or microstrip, antenna has become a common workhorse for the microwave spectrum from about 1 GHz to tens of GHz. This type of antenna consists of two conducting layers separated by a dielectric to form an extended capacitor by WlHDX

D3 Antenna for Field Day - D3+ High Performance Antennas for Field Day. This article describes versatile broadband wire antennas. These antennas will double your effective radiated power over a dipole, will be easy and inexpensive to build and install, and will be simple to match.

The Zeppelin antenna - It consists of a radiating wire with a length equal to the half-wave of the fundamental frequency for which the antenna is cut.

G WHIP - The 1960s mobile/base antenna returns, double G Whip for base use.

WideBand for Yaesu 817 857 897  ^pop - This software will allow you to extended TX for the Yaesu FT 857 FT 817 FT 897 and reset back to standard factory defaults.
