AN/PRC 77 Radio Set is a manpack, portable VHF FM combat-net radio transceiver manufactured by Associated Industries and used to provide short-range, two-way radiotelephone voice communication. In the Joint Electronics Type Designation System (JETDS), AN/PRC translates to "Army/Navy, Portable, Radio, Communication."
The AN/PRC-117 translates to "Army/Navy, Portable, Radio, Communication". It is a man-portable, tactical software-defined combat-net radio, manufactured by Harris Corporation, in two different versions: AN/PRC-117F Falcon II MBMMR [1] (Multiband Multimission Manpack Radio), also referred to as AN/PRC-117F-MP, covering the 30-512 MHz frequency ...
The AN/PRC-10 is an American VHF portable radio transceiver, introduced in 1951 [1] as a replacement for the wartime SCR-300 set. The AN/PRC-8 and AN/PRC-9 sets are basically the same but cover lower frequency bands.
A discone antenna is a version of a biconical antenna in which one of the cones is replaced by a disc. It is usually mounted vertically, with the disc at the top and the cone beneath.
AN/VRC-12. The AN/VRC-12 is the lowest-numbered element of a family of vehicular VHF - FM synthesized vehicular radio communications systems developed by Avco Corporation [1] and introduced around 1963 and used extensively by the U.S. military during the Vietnam War and for many years after.
Omnidirectional antenna. In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis ( azimuthal directions), with power varying with angle to the axis ( elevation angle ), declining to zero on the axis.
The AN/FRD-10 is a United States Navy circularly disposed antenna array (CDAA), built at a number of locations during the cold war for high frequency radio direction finding ( HF/DF) and signals intelligence.
A common form of normal-mode helical antenna is the "rubber ducky antenna" used in portable radios. A handheld two-way radio, with the rubber sleeve removed from the antenna. [citation needed] The loading provided by the helix allows the antenna to be physically shorter than its electrical length of a quarter-wavelength.
A random wire antenna usually consists of a long (at least one quarter wavelength) wire with one end connected to the radio and the other in free space, arranged in any way most convenient for the space available.
A halo antenna is a resonant antenna, providing best performance only around the one frequency it is sized for. On the other hand, a small transmitting loop can be tuned over a 3:1 frequency range with a variable capacitor .
