Optimum* installations have reported a Maximum SWR across each band as follows:
160m - 5:1
80m - 2:1
60m - 2.5:1
40m - 1.7:1
30m - 1.4:1
20m - 2.2:1
17m - 1.4:1
15m - 1.5:1
12m - 2:1
10m - 2.7:1
6m - 3.3:1

*An optimum installation would be where the antenna is deployed as a sloper with the high (feed point) end at 30 feet or higher and the low end at 10 feet or higher. We do not recommend installing this antenna as a Vertical due to users experiencing high noise (RFI) and unpredictable radiation patterns due to proximity of coax, which also allows for common mode feedback to increase.

Please note that many operators are reporting lower SWRs than we have presented. This is because they are mounting the antenna higher than the 6 1/2 foot high feed point that we used for our tests.

The 34 foot long Alpha J-Pole Jr Antenna can handle 500 watts PEP SSB (200W CW or 50W Digital) and is designed for 6-160 Meters. No tuner is typically needed on 15 or 20 meters, however if a tuner is necessary, the unique design characteristics of the antenna enables it to present a SWR on these and all other HF bands that is low enough for your antenna tuner to achieve a perfect match.

* 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. No Balun or air choke coil should be used at the antenna. We also recommend that you ground your tuner and rig. The manner in which coax is run from the feed point does not matter, as long as it does not run within 18 inches and in parallel to other components of the antenna system. For maximum effectiveness, keep your feed point as high as possible and run the antenna as a sloper for good NVIS and DX results, as a flat top for good NVIS results.
