Analysis

34 Foot element.
Band. SWR
6 Meters. 1,50.
10 Meters. 2,39.
12 Meters. 2,49.
15 Meters. 1,60.
17 Meters. 2,9.

80 Meters (External Tuner Required). 5,5.

Deployment 

Run the antenna as a sloped system for good NVIS and DX results, or a flat top for good NVIS results. We test the antennas at 6 feet, however higher placement will enhance DX results while lower placement will enhance NVIS.

    I have heard great things about this antenna from my Dad whom I bought it for. Customer service was quick and friendly. Would recommend both this antenna and Alpha Antennas as a company to anyone interested in Ham Radio.

    Customer service was excellent. The antenna as I have it set up produces SWR measured with a VNA lower than advertised and is performing on all bands! Thanks.

    I cannot express enough my gratitude toward Steven and his team at Alpha Antenna. My purchase experience with Alpha Antenna has been truly unique and one of a kind. In addition to manufacturing high-quality products, their customer service team goes above and beyond—even on a Sunday (sometimes it’s Steve himself!).

    I had an accident with my dipole about a week after purchasing it, and they immediately knew how to take care of the situation and get my antenna back in service. Not to mention their fast shipping—my repaired dipole was back at my house just three days later. This is a highly recommended company in my book. Thank you again!!

Q & A

Should a BalUn or air choke be installed? Q A asked on December 28, 2023

You may need one mainly if you are experiencing common mode current, especially after you have placed ferrite beads on the devices power cord that is experiencing common mode current. Note - Sometimes resolution is made by simply moving the devices power cord to a different circuit. If, for example, you still hear your own transmission coming from a pair of speakers then we recommend reading the following article: "The Need (or not) for Antenna Baluns or Chokes": https://alphaantenna.com/community/hints-and-kinks/news/the-need-for-antenna-baluns-ensuring-efficient-signal-transmission/

How high should this antenna be installed? Q A asked on December 28, 2023

To enhance NVIS, mount the element lower than 8 feet in a horizontal configuration. For better DX, mount the element in the clear and sloped into the direction you want to launch your signal. For example, with one end at 6 feet and the other at 30 feet (Note that higher typically results in more DX). Again, the slope helps determine the angle and direction that your signal is launched.

Regarding the 2 parallel elements that for the shape of a ‘J’; Is the 2nd wire a transmitting element like a dipole or is the 2nd element a counterpoise, and are both wires strung along the same axis or is the 2nd one sloped down beneath the 1st one at a steeper angle? Q A asked on December 7, 2023

The JPole (Jr & Sr) are derived from a fan dipole’s design, which simply enables RF to select the element(s) with the path of least resistance for the resonance required to provide acceptable SWRs. The second shorter element is an active element that that is attached to the longer element in a zip cord configuration. This enables the end fed JPole antenna to have access to 3 electrical lengths of wire. These lengths are: 1) The shortest element, 2) the longest element, 3) and an even longer combined length of 1 and 2. Then an inductor matches the impedance at the point where your 50-ohm coax attaches to the match. Operationally, the JPole Sr is designed with the optimum lengths of elements, and the 34-foot JPole Jr was designed for those who do not have the room to deploy a 60-foot JPole Sr antenna.
