The Chameleon SA-1 is a compact easy to use antenna analyzer that will help you measure SWR and tune your multi band antenna, like the Chameleon PRV System or Wolf River Coil Silver Bullet 1000. The meter measures SWR from 1:1 – 19.9 in a frequency range of 1.6 MHz to 160 MHz.

The Chameleon SA-1 is a compact lightweight SWR analyzer that would be perfect in your portable antenna kit. Opening the box you will find, a Nine volt battery, a BNC to UHF adapter, and the unit itself enclosed in a protective velvet bag.
The SA-1 has a continuous frequency range of 1.6 to 160 Mhz so it will be able to test the SWR for anyHF and VHF antennas in the amateur radio bands. It can also display the SWR from 1:1 up to 19.9:1 for that antenna. Run time with the battery is approximately 20 hours or 15 hours when you use the back light.
On the top of the meter is a small power switch, a BNC antenna port, and a socket that is labeled serial. We’ll talk about the serial feature in a bit. But first let’s look at the front of the unit
The SA-1 does not come with any instructions. Instead, everything you need to know to operate the meter is screen printed on the front of the unit. When you power on the meter, you will see the frequency and SWR on the dot matrix LCD display. Every time you turn on the unit, the frequency also defaults back to 14,000 Mhz. To adjust the frequency, you first tap the knob to select the digit and then rotate it to change the number. The unit is constantly testing the SWR, so there is nothing else you need to do. If you want to toggle the backlight, press and hold the center knob. That’s it. The SA-1 does one thing, and that’s measuring SWR. so there is nothing else you need to set it up.
A single function meter like this can be really handy in the field as it doesn’t distract with unnecessary features. It’s all in the goal of getting on the air quickly. So let’s see how fast we can do that as I demonstrate setting up and adjusting a multiband vertical antenna.
