Owner financing is an arrangement in which an owner or seller, rather than a bank or mortgage lender, extends financing to a buyer. This can be a viable option for buyers who don’t qualify for a ...
An amateur radio repeater system consisting of a 70 cm repeater and a 2-meter digipeater and iGate. Coaxial cavity RF filter at 2 meter repeater An amateur radio repeater is an electronic device that receives a weak or low-level amateur radio signal and retransmits it at a higher level or higher power, so that the signal can cover longer ...
The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.
Sometimes a transmission range of over 100 kilometres (60 miles) can be achieved through the use of a repeater. Repeaters are on channels 1–8 and 41–48 and the duplex button should be pressed to access the repeater. [5] All repeaters can be used by anyone, except for channel 5 repeaters, which are for emergencies only.
In same-band repeaters, isolation between transmitter and receiver can be created by using a single antenna and a device called a duplexer. The device is a tuned filter connected to the antenna. In this example, consider a type of device called a band-pass duplexer. It allows, or passes, a band, (or a narrow range,) of frequencies.
A duplexer is an electronic device that allows bi-directional communication over a single path. In radar and radio communications systems, it isolates the receiver from the transmitter while permitting them to share a common antenna .
Diplexing is used to prevent intermodulation and keep reflected power to a minimum for each input transmitter and frequency.While diplexers can combine a relatively wide bandwidth, the major limitation comes with the antenna itself, which must be sufficiently wideband to accept all of the signals being passed through it, and transfer them to the air efficiently.
