G7LRR Low Band Antennas - G7LRR Amateur Radio Site,160m Helical Antenna

3 element 50 Mhz Yagi - A 3 elements long yagi antenna for 6 meters band by ON6MU

Squalo 6M horizontal omni antenna - An almost Omni directional horizontal antenna for six meters by G8UBJ

6 Meter 5/8 Wave Vertical Antenna - The G3JVL 6 Meter ground plane vertical is a compact antenna that is ideal for portable operations. If needed, it can be disassembled into a very small bundle no longer than the longest element.

70cm Longyagis - 70cm-Longyagis in 28Ohm-DK7ZB-Design

Inverted Vee monoband antenna - This project will enable you to build a monoband long wire inverted vee with 3/4 wave length sides that will have a bit of gain

K9AY Flag Pennant Ewe - Elongated Terminated Loops, usage and details by K9AY Lewallen

Quad antenna calculator  ^updated - To get the dimensions for your quad, all you have to do is type in the center frequency of the range where you talk, or the frequency you use most and then click the Calculate button.

AMANDX Dipole - The longwire antenna is a very effective antenna for the listener who wants to cover all of the shortwave bands from 530 KHZ to 30 MHZ.a

Parabolic Discone antenna - This is the highest gain omni design the world may ever know having wide bandwidth

DK7ZB 144 mhz Yagis - High gain, good pattern and acceptable bandwidth. These aims can be realized with a radiation-resistance of 25-35Ohms, because the 28-Ohm-feedpoint is very simple to match.

6m Half wave vertical - This antenna is very useful for receiving or scanning purposes, but you can use it for transmitting, too. It is 2,94m long and has a pi-configuration (Collins-Filter) for the matching.

The FD4 (FD3) Windom Antenna  ^pop - The 4-band Fritzel model FD4 is a special version of a Windom antenna. It is a half-wave long on the lowest frequency, and is fed from a coax cable through a transformer inserted in the wire at one-third from one end

ON6DP QSL-Manager-Database - Qsl manager database files to download in multiple formats along to IOTA reference and other utilities

Minnesota - Willmar Police & Fire-EMS Scanner Feed - WILLMAR MN KANDIYOHI CO. Police fire EMS highway dept.

6m technical docuemnts - A collection of scanned diagrams and designs, documents and modifications for 50 Mhz ham radio equipment

A new method of radio direction finding Priority listing - A method of finding radio sources with antennas based on omni-directionality (the less directional the better coverage). Uses energy levels and some sophisticated math (encompassed in a free software download on the site) to find x,y,z coordinates of the fox relative to the center of your antenna array. Can be overlayed on a GPS map to help you locate in real-time.

Radio Sport Canada Zone to Zone propagation - ZoneProp produces a 40 zone by 40 zone matrix that is updated hourly at approximately 20 minutes past the hour. The intersection between a row and column gives the band on which a constestant in the zone represented by the row is mostly likely able to contact an contestant in the zone represented by the column.

BEIJING ELJVT - Sell the China made electron tubes over a long period of time, the vacuum tubes/electron valves/Power tubes/Audio Tubes/Thyratrons/Magnetrons and accessories, the tube sockets, the vacuum capacitors, high voltage ceramic capacitors, aluminum electrolytic capacitor.

Pizza - This program allows both great-circle (polar) and rectangular projections of the world. The great-circle map is centered on any specified latitude and longitude (the "home" location). The rectangular projection is shown with the home longitude in the middle of the screen.

MU-Locator - This free program displays the location of any locator on a map. It calaculates between two Maidenhead locators the distance (km and miles) azimuth longitude latitude Show the location, direction and distance as you move your mouse on a map! Graphical Locator Program, By ON6MU

TinyLocator - This free program calculates the location of any locator. It calaculates the distance, azimuth, longitude and latitude between two Maidenhead locators. Converts longitude/latitude coordinates to Maidenhead locator Converts Maidenhead locator to longitude/latitude coordinates
