The DirecTV Single Wire Multiswitch (SWM) is a specially designed piece of hardware that allows a DirecTV satellite dish signal to be split and used with many different tuners/receivers. The usual configurations allow 5, 8, 16, or 32 connections to a single satellite dish. DirecTV SWM is useful because of the satellite dish’s previous configurations, where lines were run to the household or location. The satellite dish had to send out a dedicated line that would power a single tuner/receiver. If a DVR was used, two dedicated lines would have Read More

PIO is Programmed I/O. PIO is the oldest method is transferring memory over a IDE/ATA interface. The technique of a PIO involves using the CPU and support hardware to control the transfer of memory between the system itself and the hard drive. The speed of the PIO is called a PIO Mode. It starts at Mode 0 and increases with each mode having a faster cycle rate in nanoseconds. So, quite obviously, higher modes are better due to the fact that memory can be transferred so much faster due to Read More

In antenna engineering, a dipole is the most basic type of antenna and serves as basic framework for all other antennas. Dipoles consist of a metal rod that acts as a conductor with a radio feed line at its core. The conductor splits the signal and creates a positive electrical charge on one end of the dipole and a negative electrical charge on the other end. Thus, a dipole is an antenna with two (di) poles. This allows the dipole to create an electromagnet wave that can be picked up Read More
