Build as a lambda/2 antenna no counterpoise or radials are needed.Mounting:With proper mounting no antenna tuner should be required. The use of a counterpose or radi-als is not neccessary.The V.S.W.R. values can vary, based on the enviroment. The length of 17.9m/59ft is ideal forcramped places, compared to other antennas for these bands.Please use guy ropes for mounting.Tuning:The antenna is delivered resonant. The resonant frequency is at the beginning of each bandand the tuning was done as an Inverted-V with an 10m glass-fibre mast. Normally there shouldbe no tuning required. However, based on influences of the enviroment, a small adjustment maybe needed. |
