Chameleon Antenna Products ......................23 Be aware of overhead power lines when you are deploying the CHA PRV. You could be electrocuted if the antenna gets near or contacts overhead power lines. Photographs and diagrams in this manual may vary slightly from current production units due to manufacturing changes that do not affect the form, fit, or function of the product. -
Page 3: Introduction
Thank you for purchasing and using the Chameleon Antenna Portable Resonant Vertical (CHA PRV) antenna. The CHA PRV is a finely crafted lightweight and rugged antenna -- intended for extreme portable use, such as: Parks On the Air (POTA), Summits On the Air (SOTA), and other outdoor radio adventures where an efficient but highly portable antenna is required. -

The most important thing The MUF is the frequency for which for the operator to understand about HF successful communications between two CHA PRV Page 4... - Page 5 Therefore, NVIS propagation can normally only be used on frequencies from around 2 to 10 MHz. Frequencies of 2 – 4 MHz are typical at night and 4 – 8 MHz during the day. The CHA PRV, like most vertical antennas, is not designed to utilize NVIS propagation.

Page 6: Cha Prv Sota Kit Components
CHA PRV SOTA Kit Components The CHA PRV SOTA kit is comprised of the following components, see plates (2) and (3). Plate 2. Antenna Components. A. Multi-Configuration Coil. The Multi-Configuration Coil (CHA MCC) provides base-loaded inductance for the vertical antenna and is continuously adjustable for resonance at the operating frequency. - Page 7 F. Coaxial Cable. Coaxial Cable is 12 feet of RG-58 with an integrated RF Choke. It is used to connect the CHA PRV to the Radio Set. Longer lengths available as options. This antenna requires an RF Choke in the feedline.
- Page 8 N. Insulator Ring. An Insulator Ring is located at the end of each Counterpoise Wire. O. Variable Length Counterpoise. The Variable Length Counterpoise is a highly flexible method of providing the CHA PRV a necessary counterpoise from 5.3 to 54.0 MHz (60 – 6 meters).

Page 12: Operation Of The Portable Resonant Vertical
Operation of the Portable Resonant Vertical We’ve made operation of the CHA PRV easy. When using the basic antenna, it is tuned on 40 through 10 meters only by adjusting the height of the Multi-Configuration Coil and selecting the number of Counterpoise Wires. Use the following procedure to tune the CHA PRV. - Page 13 The initial settings in tables (2) and (3) were made in a typical operating environment, but could vary greatly from your values. Plate 5. Tuning Adjustment. CHA PRV Page 13...

Page 14: Operation On 6 And 2 Meters
Figure (2). Tuning Chart (40 – 10 meters). Operation on 6 and 2 meters The CHA PRV can be used on the 6 and 2 meter ham bands. To operate on these band: • Fully lower the Multi-Configuration Coil. • On 6 meters, install one or more Counterpoise Wires per that are ¼ wavelength long or use the optional Stinger Kit. -
Page 15: Tuning Theory
Figure (3) shows an actual photograph from an antenna analyzer for the CHA PRV tuned for 20 meters. When you initially set the height of the Multi- Configuration Coil, using Tables (2) or (3), you don’t know which region on the graph you will be, as an SWR meter only provides a number. -
Page 16: Recovery Procedure
Recovery Procedure To recover the CHA PRV, perform the following steps: 1. Disconnect the Coaxial Cable from the radio set and antenna. 2. Carefully roll (do not twist) the Coaxial Cable. 3. Unplug the Counterpoise Wires from the Puck hub. -
