No special rules apply if your antenna structure will be less than 300 feet in height.
You must file an Environmental Impact Statement with the EPA before construction begins. You must obtain a construction permit from the airport zoning authority
The FAA must be notified and it must be registered with the FCC
Approval must be obtained from the airport manager
Approval must be obtained from the local zoning authorities
The FAA must approve any antenna structure that is higher than 20 feet
To build a radio you will need a receiver and a sender. This would be an antenna and some radio station sending a signal. You will also need an amplifier or speaker to hear the translated signal from the radio station. With all of these and an understanding of physics, you can build a radio, which was something I did freshman year of college.
The half-wave, center-fed 'dipole' antenna is probably the antenna that's simplest to design, and easiest to build and operate. For 100 MHz, it's a single wire, supported at its ends and insulated from the supports, hung horizontally, opened and connected to a 75-ohm coaxial cable at its center, with an overall length of 4 feet 11 inches (1.5 meters).
A vertical antenna, like a piece of wire, connected directly to the radio, works well if it's 1/4 of the wavelength of the signal being received. If it's a horizontal wire hanging between a couple of trees, with a coaxial cable connected to a gap in the middle of the wire, then it works best when its overall end-to-end length is around 1/2 of the wavelength. 1/4 wavelength in feet is around: (246) divided by (frequency of the signal in MHz) 1/2 wavelength in feet is around: (492) divided by (frequency of the signal in MHz) The frequency of red light is around 462,000,000 MHz. So for good efficiency, the half-wave antenna should be about 0.00000107 foot long, or 0.0000128 inch. If you have a radio receiver capable of tuning to the frequency of red, I'll personally come help you trim the half-wave antenna to pick it up. In fact, I'll build you a by-George 100-element Yagi !
Not familiar with your car, does your car have a fancy compass on the rearview mirror? Or perhaps an antenna build into it? Or maybe just lights underneath the mirror. That'd be a good place to start. If not, something was probably knocked loose or disconnected during installation. If you haven't already, try checking fuses and the like.

If the player enables radio it should use either an in built antenna of use the earphones as an antenna. Nothing more to buy or build.

Yes, a resident can buy or rent land and build an airport to own and run, alternatively there are many existing airports within second life that may recruit people interested in airport management. Most airports are located in the Blake sea regions that are ideal for flying in.
sure its called a hanger

== == For digital TV, you can build a DB4 antenna out of wire coat hangers and a piece of wood. Very simple to make. There are step by step instructions here - www.TheTutorGenie.com/DigitalAntenna.html - It works great. It depends on what you want to do with it. A receiving antenna for 40 m shortwave could be just a long piece of wire tacked to the walls. An antenna to transmit and receive at 440 MHz is a completely different animal.
