Default QUESTION - Does a "Non-Resonant" Dipole Antenna work better {Benefit} when a Receiver is RF Grounded in the Shack ? ? ?

For One and All,

Per "Telamon" - A Hertzian Antenna such as a Dipole has two elements
that develop the Voltage across the Receiver Input
- - - So an RF Ground becomes superfluous.

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.
