Antennas for Autotuners - 0 views

  •  
    The goal was simple: Using the autotuner, tune the most number of bands with the highest efficiency on a doublet antenna. Getting the highest efficiency mandates the use of ladder line because SWR loss can be very high using coax on multiband antennas.

the REAL SWR page - 0 views

  •  
    "This page is all about Where the energy really goes in an antenna system. Will a high SWR blow up my transmitter? ( No, it will not, but POOR TUNING can.) ---The Reflection Section--- The purpose of this section is to explain what happens when un-used energy comes back down the coax from the antenna. "

Cebik antenna and other short limited space dipole antennas - 0 views

  •  
    "A good rule of thumb is length in feet must equal 1.25 times the band in meters. The result is the minimum dipole length you can use without using a good matching system in, at, or near the antenna!"

ASAP Examples: Feedlines - 0 views

  •  
    "When considering the effects of feedlines it should pointed out that it is often not appreciated that a coax cable is really three conductors at RF. The three are: 1. the outside surface of the inner conductor, 2. the inside surface of the outer conductor, 3. the outside surface of the outer conductor. The outer conductor of the coax is just as much a "wire" as any other wire in the system. It is not necessary, however, to model the inner conductor and the inner surface of the outer conductor. So the coax is just modeled as another wire. "
