A portable tool used to find or tune television satellites is known as a satellite finder. It’s also referred to as a satellite pointer or a dish pointer. The signal intensity of several satellites in geostationary orbit is measured by a satellite finder.
The Global satellite finder market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Digital satellite finder by electronicsforu. The utility of using a satellite finder is that it allows users to get the full spectrum of channels from all active transponders on a given satellite using the low noise block (LNB) down-converter used for satellite reception (digital or analogue).
When the dish is appropriately aligned, a contemporary LNB feeds a significant amount of RF energy to the receiver in addition to its high gain.
The Received Signal Strength Indicator (RSSI) output from the digital satellite finder, which is produced by adding the power from all transponders, is used to represent the quantity of RF energy over a broad frequency range.
Since the majority of the currently available satellite finders only use analogue scales, some of them are partially digital (digital handling with analogue display), and the few, expensive, and infrequently available digital satellite finders, creative design explores the most recent RF power measurement (RSSI) with digital readout technology.
This yields beneficial results for dish TV installers.The Linear Technology IC LTC 5508 is used to detect RF power. The input power range for the LTC5508 is -32dBm to 12dBm. For RF applications working in the 300MHz to 7GHz band, this IC serves as an RF power detector.
In a compact SC70 package, a temperature-compensated Schottky diode peak detector and a buffer amplifier are integrated to detect RF power using dc output voltage. The voltage that was detected is buffered and delivered to the VOUT pin.
Peak output voltage is created by an RF signal at its strongest.In order to perform RF power detection over frequencies spanning from 300MHz to 7GHz, the LTC5508 RF detector integrates a number of functionalities.
