Antenne Speciali HF VHF UHF In questa sotto pagina verra' illustrato come costruire antenne VHF per portatili che non seguono i dettami teorici ma solo la pratica e sono basate sostanzialmente su tre principi fondamentali che sono: BASSO COSTO, COMPATTEZZA ed EFFICIENZA.. With a little bit of knowledge and some basic tools, you can create an antenna that will capture signals from both UHF (Ultra High Frequency) and VHF (Very High Frequency) bands, offering you a wide range of channels to enjoy.

For VHF/UHF commercial antennas you are virtually guaranteed to have something close to a 50 ohm feed point as long as you keep the antenna away from other significant conductors in the environment by a wavelength or two. (You probably don't want to mount your vertical antenna right next to the vertical aluminum downspout on your house, for. So, because VHF and UHF antennas work due to the principles of physics & radio wavelengths, you will generally find these antennas in 4 common lengths: Shortened VHF UHF antennas that are up to 50 centimeters long = -3dBd 1/2-wave (dipole) antennas that are approximately 1 meter long = 0dBd Click HERE for Reviews. This is a full-size rigid antenna, which a single mast or our tripod will support, and deploys as either a vertical or dipole that covers VHF/UHF/HF on 2 to 40 meters plus 220MHz, & 440MHz.

Step 1. Coaxial Cable. Let us first start with the coaxial cable. Take the coaxial cable and measure up to 21 or 22 inches of the coaxial cable and make a mark of it. Step 2. Outer Insulation. Next, remove around 21 or 22 inches of the outer insulation portion of the coaxial cable measured above. Step 3.

A VHF antenna receives television signals in the VHF frequency band (54 - 216 MHz). VHF antennas typically have larger elements to capture the longer wavelengths of VHF signals A UHF antenna receives television signals in the UHF frequency band (470 - 608 MHz). 204 Share 42K views 5 years ago Va bene sul super efficiente ho un po barato ma d'altra parte con un pezzo di filo e un connettore che volete? L'antenna comunque ha un buon guadagno in UHF lavora.

That is, the element lengths are those used with a wood or plastic (dielectric) boom or supported above or below a metal boom with an large insulator. To convert these raw lengths into actual lengths used when passed through the center of metal booms, you need to add a.
