END FED INVERTED “L” ANTENNAFOR <strong>160</strong> – <strong>80</strong> – 40 METRES3-D Far Field Total Radiation Plot for 7.05 MHz.The 3.55Mhz &1.92MHz plots are very similar. The “funnel” in the centre gradually disappears. In all three cases themaximum radiation is at an angle of about 30 degrees to the ground.(see results below)MMANA-GAL MODEL RESULTSn<strong>G0CSK</strong> EA5AVLThe model only provides an indication of the expected performance of this antenna.In practice better SWR results & hence improved efficiencies can be obtained.G8ODE OCT 2008 <strong>iss</strong> 1.1
