Fundamentals of Antennas
1. Basics - How an antenna Works, The Dipole.
# Wavelength.
# Dipole is fundamental Antenna.
# Dipole Pattern.
# Rabbit Ears are Dipoles.
2. Common TV and FM antenna Types.
# Bogus Antennas.
# Dipoles, Folded Dipoles.
# Twin Lead.
# Rabbit Ear.
* Getting Away From Interference.
* Wave Length Table.
* My Rabbit Ear Solution (VHF & & Half Rhombic UHF)
# Turnstile
# Other Omni
# Yagi
# Log Periodic
# Typical TV-FM VHF Only Home Antenna
# Typical UHF Only Home Antenna
# Typical All Band Home Antenna
# More Antenna Types From HF to SHF Covered in Navy Electronic Warfare Training Manual
Use and Installation
3. Enviromental Factors
# Environmental Factors. Wind and Sea?
4. Clearance, Stacking and Combining.
# Attic? Why not?
# Stacking.
# Required Clearance to Other Stuff.
# Stacking can null interference.
5. How to Get More Out of Rabbit Ears.
# Channel Frequency Length List.
# How to Adjust Rabbit Ear Antennas.
# Keeping them away from the TV set and other computers.
6. Which way to point the antenna.
7. Amplifiers, the Good, the Bad and the Ugly.
# Basics, noise figure, output power capability and gain.
# Why not to use an amp.
# Why to use an amp.
# Indoor Outdoor.
<edit> also goto http://global-cm.net/distribu.html for an interesting treatise on signal distribution.
