2 m, 4 m and 6 m
|The Delta-Loop has the parts B longer then A. The reason is a
little bit higher gain and an impedance of 110 Ohm. The
transformation to 50 Ohm is made with a quarterwave section of
75-Ohm-cable RG59 B/U. The spreader is a PVC-pipe with 25 mm
diameter. The wire is PVC-insulated copper braid 1,5 mm2.
In the right picture you see two current maxima, the loop is astacked system with a gain of 0,95 dBd.
