VERSATILE Alpha EndFed HF J-Pole Antenna 500 watt for 10-80 Meters
The Alpha J-Pole Jr EMCOMM Antenna is only 60 feet in length. The unique design
characteristics of thIS 6-160 Meter HF JPole antenna enables it to achieve
resonance on the major HF bands (10/12/15/17/20/40/80 Meters) and presents a SWR on 80 and 160 Meters that is low for external tuners to achieve a perfect match.
Weight: 1 pound
Configuration*: End-fed configurable as Sloped or Horizontal
Frequency Coverage: 3.5-29.7 MHz (80-10 Meters without a tuner per bands on chart & can be used on 160 & 6 meters with an external antenna tuner)
Power Rating: 500 watts
Length: 60 Feet
The following analysis for the Alpha EndFed HF JPole were taken at a height of 6 feet 6 inches and at the antenna with a 12 inch section of coax.
*This antenna should be installed as a sloper or in a flattop arrangement. We do not recommend installing this antenna as a Vertical due to verticals being inherently prone to high noise (RFI) and unpredictable radiation patterns due to proximity of coax, which also allows for common mode feedback to increase.
