JD,
The G5RV is a good Antenna and an Off-Shoot of the common Dipole. ALL TRANSMITTING THEORY ASIDE: * For SWLs think of the G5RV as a Dual Opposing Inverted "L" Antenna with common mode vertical (dual element) Leg. - Here the G5RV is more Omni-Directional. * For SWLs some specific Frequencies the Top Arms of the G5RV Antenna function like a Dipole that is 'cut' for that Band or Bands. - Here the G5RV is very 'directional' Dipole.

The most 'common' form of the Random Wire Antenna used by SWLs is the Inverted "L" Antenna. This Inverted "L" Antenna Configuration lends itself to the Low Noise Antenna design that was popularized by John Doty.

You Can Hear Forever and beyond, The Beyond ! .. = = = (John) = = = wrote in message . com... Need a little help here. I've been using a G5RV for a number of years for my receivers and it does a very good job. But I notice that many folks here seem to prefer a long wire. Is there much difference between a long wire compared to a G5RV or dipole? And if using a long wi wouldn't a long wire need to be electrically matched to the receiver? Or, by using a G5RV, am I essentially using 1/2 of the antenna as a long wire (the center portion of the antenna jack on the receiver so to speak). Is one antenna really that much better than the other? As I said, I've been using a G5RV for quite a long time and I feel I can pick up just about the same things other folks do; so I don't believe changing to a long wire would dramatically improve my reception. But then again, I might be wrong. Any help would be appreciated in understanding the difference between the antennas a bit better -- if there is any. John .. |
