To cut a wire or aluminium tubing length for a dipole antenna take your frequency in Megahertz that you want to tune the antenna to and divide that number by 468. This will be the full wave length of the frequency you will be tuning to. For general purpose listening cut the antenna to mid frequency of the FM band. Cut this wire (or tubing) into two equal pieces. This will be the driven element feed point. For a yagi antenna cut a reflector 10% larger that the first cut and place it 1/2 wavelength behind the driven element on the boom. For the director cut the wire length (or tubing) 10% smaller that the driven element and place it on the boom 1/2 wavelength in front of the driven element. This will give you a three element yagi antenna.
What else can I help you with?
Is electricity needed ta make an external antenna work?
No, an external antenna can work without electricity. It simply picks up radio frequency signals from the air and sends them to the device it is connected to. The device, such as a TV or radio, uses its own power to process and display the signals.
Can a satellite dish be put in an attic like a broadcast antenna?
No, not really. The satellite signals are much weaker than broadcast signals and they will not make it through solid objects such as a roof. You can get the antenna installed completely free if you shop around, and federal law allows you to put the antenna up, invalidating most local ordinances and covenants restricting them. If you are a renter, you can't make a permanent modification to the property (like drilling holes for the antenna) without permission of the owner. Renters have had some success positioning the antenna in a window with a clear view of the southern sky but that is only for the desperate.
what does a cordless phones mean?
A cordless telephone has a handset that is powered by a rechargeable battery and transmits with an antenna rather than a chord. This allows the user to carry the telephone with them to make and receive calls anywhere in their home.
With what materials did Guglielmo Marconi make the first radio with?
Guglielmo Marconi made the first radio using a transmitter, receiver, and antenna. The key components were a spark gap transmitter, a coherer receiver, and long wire antennas to send and receive wireless signals.
How do you watch TV in your desktop PC?
Channels can be received either over the air using an antenna or through cable from your cable TV provider. Make sure which signals you can receive in your araa. Then you need purchase a digital tv tuner card. such as TBS Series tv card.
How do you make a ipod touch get phone signals and use it?
You cannot turn an iPod Touch into a phone and make it receive phone signals. The iPod Touch does not have the hardware and software capabilties to do so.
Extending The Range Of A Wireless USB Network Adapter?
A wireless adapter that uses a universal serial bus (USB) connection gives a business the flexibility to make any computer or laptop a part of the wireless network. A wireless USB network adapter relies on a limited amount of power when it is attached to a laptop or other device. This can sometimes restrict the range of the adapter. One way to extend the range is to change the antenna on the unit. A wireless USB network adapter uses some type of antenna to send and receive signals. This antenna can often be removed and replaced from the unit. The most common type of antenna on a wireless USB network adapter is an omnidirectional antenna that receives signals in all directions. A much stronger connection can be maintained across a longer distance with a directional antenna that focuses on signals coming from a specific location. These antennas are inexpensive and very effective in an office environment. Unfortunately, this will not work with a wireless USB network adapter that contains an integrated fractal antenna that cannot be replaced.
What receive signals from molecules and make sure the Right cell gets the right signal at the right time?
lysosome
How do you build a simple home use antenna?
== == 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. Here's a fun web site: http://www.ac6v.com/antprojects.htm
How does a smart phone receive a signal?
A smartphone receives a signal through its built-in antenna, which communicates with nearby cellular towers. These towers transmit radio waves that carry voice, text, and data signals. When you make a call or use the internet, the smartphone decodes the received signals and converts them into audio or data for you to use. Additionally, smartphones can also connect to Wi-Fi networks for internet access, using different frequency bands.
How do you make a scanner antenna?
You don't.
If your power antenna on a '91 lesabre jams up but the motor keeps trying to make it go down how can you stop the motor and fix the antenna?
unplug the electrical from the antenna. replace antenna.
