WebAttenuators are passive devices. It is convenient to discuss them along with decibels. Attenuators weaken or attenuate the high level output of a signal generator, for example, to provide a lower level signal for something like the antenna input of a sensitive radio receiver. (figure below) The attenuator could be built into the signal ... Web6 nov. 2024 · In most cases you will see that the further you move the transmitter away (in frequency) the better. The 6 meter repeaters in some areas have 1 MHz offsets where others have 0.5 or 0.6 MHz offsets, and those that have 1 MHz have it easier. Many others have found that the 5 MHz offset on UHF makes it much easier to duplex than the 0.6 …

Web13 jun. 2024 · At 30 MHz a wavelength is 10 meters or 33 feet. Thus 4 times 33 equals 132 feet. So my 150 ft is off by 12%. Not bad for a quick guess. Again, the point was to illustrate that if you have a structure with a transmit antenna at 40 ft and a receive antenna at 60 ft, then you might expect 40 to 50 dB isolation. http://ok1teh.nagano.cz/eme_gal432.htm Web432 MHz Loop Feed, VLNAs & Cavity filter PVC water proof box SPINER relay and first LNA 0,35 dB N/F Box and relay "SPINER" Cavity 5 stage filter + second LNA All parts in box before final painting of feed and wiring January 2010 In cooperation with Petr chuck taylor high tops sale
