Antennas make the difference! The pictures below illustrate my point:


A 4 bay array of 1296 loop yagis, with 7 wavelength 222 and 2.5 wavelength 11 element 50 MHz antennas. This is a ninety foot tower.



A 4 bay array of 5 wavelength 144 mhz antennas for EME and a 5 element monobander for 10 meters in the background. The horizontal cross boom on the EME array is about 20 feet high.



View from the bottom of another 90' tower; the antennas on the top are shown in the picture below, and the bottom antennas are shown in the bottom picture.



The three yagis on top are a 2 bay array or 5 wavelength 144 MHz antennas and a 13 wavelength 432 MHz antenna. Most of the rest of the antennas that can be seen are on a TIC Ring Rotator (there are a couple of end mounted non-rotating antennas for 144 and 432 packet mixed in). Those that can be rotated are short (less than 15 feet) vertical yagis for 144, 222 and 440 MHz. The others that are rotated are a pair of loop yagis for 902, 2304 and 3456. This is also a ninety foot tower.



A 7 element and an 11 element 50 MHz antenna used for contesting. They and the other 11 element are combined using a WX0B Stackmatch allowing the ability to combine all three 50 mhz antennas in any combination desired or using a single antenna by itself. They are not phased together to get stacking gain but rather are placed so as to have the ability to hear or transmit signals off the sides of the rotating 11 element (among other reasons).
