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.
An RF cable is a basic cable used primarily for carrying audio-visual signals. It is a type of coaxial cable, which involves a series of casings to protect the signal from interference. The coaxial design used in an RF cable is designed to prevent potential interference. To counteract this, the coaxial cable uses four circular layers.
