2.5:1 SWR Measured Bandwidth / Band
- 20M: 13.800 mhz - 14.440 mhz
- 30M: 10.000 mhz - 10.300 mhz
- 40M: 7.095 mhz - 7.280 mhz
- 6M: 47.800 mhz - 54.400 mhz
Antenna bandwidth was measured with ALICE HFpack on my back using a 15 foot drag counterpoise wire. A SWR figure of 2.5:1 was used because the Icom 703 Plus antenna tuner will only match 3.0:1 or slightly higher.
On 40M I had to add thirty turns near the top of the stick to get it to work on CW. My short counterpoise wire probably is the reason.
