What is a Zepp antenna?
The MFJ-1748 End Fed Zepp is an end-fed wire antenna that, when properly erected and fed with balanced feedline through an antenna tuner, will be usable on all amateur bands from 80 to 10 Meters. This antenna will handle 1500 watts of RF power (with a suitable antenna tuner). Its total length is approximately 135 feet.
Is J Pole a good antenna?
The myth is that j-poles have lots of gain and are better than anything else. A j-pole is just a 1/2 wave end fed antenna fed with a 1/4 wave transmission line matching section. If constructed and tuned properly, they only have as much gain (0 dBd) as a dipole.
Do J pole antennas have gain?
Primarily a dipole, the J-pole antenna exhibits a mostly omnidirectional pattern in the horizontal (H) plane with an average free-space gain near 2.2 dBi (0.1 dBd).
What is the gain of a Slim Jim antenna?
Slim Jim antennas have no performance advantage over the conventional J-pole antenna. The approximate gain in the H-plane of the Slim Jim is from 1.5 to 2.6 dBi (-0.6 dBd to 0.5 dBd).
