Antenna gain-to-noise-temperature ( G/T) is a figure of merit in the characterization of antenna performance, where G is the antenna gain in decibels at the receive frequency, and T is the equivalent noise temperature of the receiving system in kelvins. The receiving system noise temperature is the summation of the antenna noise temperature and ...
Noise temperature (antenna) In radio frequency (RF) applications such as radio, radar and telecommunications, noise temperature of an antenna is a measure of the noise power density contributed by the antenna to the overall RF receiver system. It is defined as "the temperature of a resistor having an available thermal noise power per unit ...
The antenna noise temperature gives the noise power seen at the output of the antenna. The composite noise temperature of the receiver and transmission line losses represents the noise contribution of the rest of the receiver system. It is calculated as the effective noise that would be present at the antenna input terminals if the receiver ...
Recreational vehicle. A recreational vehicle, often abbreviated as RV, is a motor vehicle or trailer that includes living quarters designed for accommodation. [ 1] Types of RVs include motorhomes, campervans, coaches, caravans (also known as travel trailers and campers), fifth-wheel trailers, popup campers, and truck campers . Typical amenities ...
Tower Mounted Amplifier. A Tower Mounted Amplifier ( TMA ), or Mast Head Amplifier ( MHA ), is a low-noise amplifier (LNA) mounted as close as practical to the antenna in mobile masts or base transceiver stations. A TMA reduces the base transceiver station noise figure (NF) and therefore improves its overall sensitivity; in other words the ...

7-pin round blade connector (SAE J2863) This is common for RVs and other large trailers which have additional loads beyond the basic for tail lights and brake/turn signals. The standard is defined by SAE J2863, Automotive Trailer Tow Connector . Reversing lamps, control current to block surge brakes when reversing.
The difference between the two antenna systems determines whether atmospheric scattering is by temperature fluctuations (in mono-static systems), or by both temperature and wind velocity fluctuations (in bi-static systems). Mono-static antenna systems can be divided into two categories: those using multiple axis individual antennas, and those ...
