Portable Satellite Radio Transmitter - Installation
Most air schedules lack good frequency -- that is, how many times a listener will hear your message in seven days. Stations often measure the number listeners hear your commercial over the course of the program or by the months. It should be measured by week only.

For most applications lower radio frequencies are more effective for longer range. A broadcasting TV station illustrates this. A typical VHF station transmits at approximately 100,000 watts with a coverage area of 60 miles. A UHF station that covers 60 miles requires transmission at 3,000,000 Watts.

This is what your microwave oven is. The metal mesh on the glass front door is very thin. Microwaves, which are extremely high frequency, have wavelengths that are only a few inches in length. The mesh keeps the microwaves trapped in the oven but it allows you to see inside because light waves have a microscopic wavelength.

VHF equipment is generally cheaper than UHF equipment because it is simpler to make and has been around for longer. One disadvantage to this equipment can be its size. An antenna must also be larger, as the frequency waves can be much higher.

Let us discuss the GPS dog collar. This works in the same way as the system you have installed in your vehicles today. GPS, also known to be called Global Positioning System (GPS), has been used to program the collars for dogs. The collar is placed on your pet dog's neck after you have programmed a safe zone for it to roam. You can track where your dog is in real time when it leaves the zone.

UHF equipment operates at frequencies of 300 MHz through 3000 MHz. It was not widely used up until recently. The UHF radio frequency can be used for GPS, Bluetooth and cordless phones as well as WiFi.

Radio transmitters that are small and portable are very simple to use. If you've ever used a basic car radio adapter for your iPod or mp3 player, then you can use a private radio transmitter.

visit here are transmitted in a series of cycles. You will always see the "Hz" abbreviation used to indicate the frequency of a radio. Hertz is one cycle per second.
