Is a G5RV a doublet antenna?
G5RV antenna basics The G5RV antenna is an amateur radio centre fed doublet with a symmetric resonant feeder line, which serves as impedance matcher for a 50Ω coax cable to the transceiver.
Does G5RV need a balun?
Recommendation. A balun or choke should NOT be used on a G5RV wire dipole. The classic G5RV 102 ft. wire dipole consists of 51 ft.
How high does a G5RV have to be?
Member. Going to install a G5RV 80 meter antenna (102 feet) running from a large pine tree in front yard to equally high hardwood tree in back yard. At least fifty feet above the ground. Reactive ladder line (31 feet long) will hang vertically about a two feet from back of house.
How high should a G5RV Jr be?
30 feet
The center of the antenna must be at least 30 feet above the ground in this configuration.
Will a G5RV antenna work on 60 meters?
* Well, it will work on 60 meters, if you use a 76′ length of the 420 ohm window line; SWR is below 1.5:1. Note that the SWR values in the above charts are at the antenna . Some commercial G5RV antenna designs rely on the loss in a long coax feedline to bring their claimed SWR down in lieu of—or in addition to—an antenna tuner.
Is the ZS6BKW antenna better than the G5RV?
Neither the G5RV nor the ZS6BKW antenna works on 30 or 60 meters. The G5RV does NOT work well on 17 or 10 meters. The SWR is a little better on 80 than the ZS6BKW. The ZS6BKW does NOT work well on 15 meters, and needs a tuner to work well on 80.
Is there a better alternative to the G5RV?
G0GSF (ex-ZS6BKW) came up with a similar design that is a significant improvement over the G5RV. Even that design still doesn’t cover all the HF bands
How do you reduce SWR on a G5RV antenna?
Some commercial G5RV antenna designs rely on the loss in a long coax feedline to bring their claimed SWR down in lieu of—or in addition to—an antenna tuner. You should use a ferrite-core broadband 1:1 current balun (choke) right at the junction of the window line and coax to keep RF off the outside of the coax shield.
