It is quite intriguing that most virus capsids are either icosahedral or helical in structure. Presumably, these two structures were the ideal structures to protect a viral genome and accessory proteins within a virus particle.elical Capsid. Helical capsids are usually formed from one protein that interlocks to form a helix-like structure around the viral genome. They are usually more common among viruses that infect plants, though influenza, measles, mumps and rabies viruses all have helical capsid structures.
1 RF modulator converts AV to RF channel.  Consumes 9 VDC input voltage and offers Antenna interfaces/ports for reliable transmission.
Radio Frequency Identification (RFID) is an automated data collection technology that enables equipment to read tags attached to the objects without contact or line of sight. RFID uses radio frequency (RF) waves to transfer data between a reader and an item to identify, track or locate the item. The RFID system consists of a tag, which is made up of a microchip with a coiled antenna, and an interrogator or reader with an antenna.
