Can you use a 40 meter dipole on 20 meters?
Can you use a 40 meter dipole on 20 meters?
MFJ-17754 40/20M Dipole Antennas are shortened, coaxial-fed, 42 ft. long dual-band resonant antennas. While functioning as a full-size dipole on 20-meters, it’s also an ultra-efficient end-loaded dipole on 40-meters. You may operate these dipoles at up to 1,500 watts!

Is a folded dipole balanced?
Like the basic dipole, the folded dipole antenna is a balanced antenna, and needs to be fed with a balanced feeder. Unbalanced feeders can be used provided that a balun (unbalanced to balanced transformer) is used.
How does a dipole radiate?
Dipole antenna basics The name ‘di-pole’ indicates that the dipole antenna consists of two poles or items – two conductive elements. Current flows in these two conductive elements and the current and the associated voltage causes an electromagnetic wave or radio signal to be radiated outwards from the antenna.
Can a 30 Meter Dipole antenna be used?
The coax loops through the PVC pipe to provide strain relief. by W1TR A 30 Meter Sloping Dipole Antenna – This variation of the basic horizontal, half wavelength flat top dipole has proven to be a simple, effective antenna suitable for both home and portable use.
Are there rotatable dipoles that can be expanded to beams?
Mosley rotatable Dipoles are the perfect answer for those limited with space, but want the flexibilty to expand down the road. All rotatable dipoles listed below can be expanded to beams down the road with conversion kits. As with all Mosley antennas, pieces are all pre-drilled and color coded, which makes assembly quick and easy.
What makes a Mosley antenna a better antenna?
Mosley, A BETTER ANTENNA! Automatic band switching by means of high-impedance resonant trap circuits. Mosley rotatable Dipoles are the perfect answer for those limited with space, but want the flexibilty to expand down the road. All rotatable dipoles listed below can be expanded to beams down the road with conversion kits.
Is there a warranty on Mosley rotatable dipoles?
The warranty is two year against any defects of material or workmanship. For MONO-BAND Rotatable Dipoles CLICK HERE! Mosley reserves the right to change product and material specifications without prior notice or obligation.
