Install your antenna properly

K9AY loop antenna

Developed in the early 1990's by American radio amateur Gary Breed.

Laptop Mini Wireless Antenna

A small antenna to boost the signal of a laptop wireless card, that can be stuck to the back of the laptop screen.

Log Periodic Antenna Design

This is a Java applet which calculates the dimensions and spacings of the elements needed to build a log periodic antenna, given tao, sigma and the lower and upper cutoff frequencies.

Long Loopstick AM Radio Antenna

Wound on a3-foot length of PVC pipe, the long Loopstick antenna was an experiment to try to improve AM radio reception without using a long wire or ground. It works fairly well and greatly improved reception of a weak station130 miles away. A longer rod a

Loop Antenna Design

The design frequency, the feedpoint impedance, will be between 80 and 150 ohms. Coax fed loops will usually have an SWR between 2:1 and 3:1. You may feed this antenna with a 4:1 balun. If the loop is in the shape of square or large rectangle, the SWR can be below 2:1

Loop Antennas

Different active and passive loop antennas, performance, construction and comparison.

Low Cost Satellite Antennas

All you need to build a simple VHF or UHF 1/4 wave groundplane antenna is a coax chassis connector and number 12 or larger wire scraps. Solder the vertical element to the center conductor and attach the radials with nuts and bolts to the four corners, then solder each corner.
