This Statement may be True a the specific Frequency that the Dipole is Designed to Operate at {Resonance} . "IS" this Statement always True at other Frequencies that the Dipole was NOT Designed to Operate at {Non-Resonant} ? Certainly is, the point is a dipole is a balanced antenna, i.e. a signal impinging on the antenna will have two components that 180 degrees out of phase. Thing about which end of each half the feed comes from. So one side will always be the opposite orientation from the other side. All that happens when the antenna is not resonant, is the effective impedance changes, and will contain a reactive component. That usually reduces the power transfered from the antenna to the front end of the receiver. QUESTION - Does a "Non-Resonant" Dipole Antenna work better {Benefit} when a Receiver is RF Grounded in the Shack ? ? ? http://groups.yahoo.com/group/Shortw...a/message/9189 i want to know - cause iane ~ RHF .
