A Motorola connector (also called a Motorola antenna plug [citation needed] or a male DIN 41585 [1]) is a common coaxial cable RF connector used primarily in the automotive industry for connecting the coaxial feedline from the antenna to the radio receiver. It is also sometimes used for connecting scanner antennas to scanners.
The IC-7100 allows for connection to a computer over USB which enables the radio to be used for popular digital modes such as FT8, Winlink, and Packet Operation. [3] Locations of nearby repeaters and sending APRS locations can be done with an optional GPS receiver attachment. [1] Notable features that the IC-7100 lacks is an internal antenna ...
A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...
Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. [ 1 ] : p.149 [ 2 ] The individual antennas (called elements ) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase ...
Indoor antennas are designed to be located on top of or next to the television set, but are ideally placed near a window in a room and as high up as possible for the best reception. [1] The most common types of indoor antennas are the dipole [2] ("rabbit ears"), which work best for VHF channels, and loop antennas, which work best for UHF. [3]
If the auto scan does not pick up the signal and the tuner has manual frequency scan capability try to get the actual frequency from the station engineer. This may allow one to stay on one frequency (channel) versus "scanning" (moving too quickly through) and allow one to make antenna adjustments while observing only a problematic channel.
In a C-band antenna setup, the transmission frequencies are typically 3.7–4.2 GHz. By using a local oscillator frequency of 5.150 GHz the IF will be 950–1,450 MHz which is, again, in the receiver's IF tuning range.
