Introduction to Communication Systems and Networks

Aug 31, 2010 · A channel is a path between two communication devices ! Channel capacity: How much data can be passed through the channel (bit/sec) ! Also called channel bandwidth ! The smaller the pipe the slower data transfer! ! Consists of one or more transmission media ! Materials carrying the signal ! Two types: ! Physical: wire cable !

“The 2:1 SWR bandwidth is 3.5 to 3.8 MHz.” Popular amateur usage of the term “bandwidth” most often refers to the 2:1 SWR bandwidth. Other specific bandwidth terms are also used, such as the gain bandwidth and the front-to-back ratio bandwidth. For the most part, the lower the operating frequency of a given antenna design, the narrower ...

SWR at both ends of the band equal. This adjustment only moves the SWR a small amount. REMEMBER THIS ANTENNA REACTS TO EVERYTHING IT CAN SEE. THIS MEANS THAT TREES, POWER LINES, BUILDINGS, AND OTHER ANTENNAS AT THE SAME HEIGHT WILL AFFECT THE SWR. THE V58 CAN BE TUNED MOUNTED 6 FEET OR SO ABOVE THE

The stub length for tuning z 1 to 1 requires l 1 = 0.478 , And for tuning z 2 to 1 needs l 2 = 0.022 Figure 5: Short circuited stub in shunt [3] Z Example 2 For load impedance Z L
