We are happy to answer any questions you may have about the HexTenna. Here are some of the frequently asked questions:
1. QUESTION: Why is the vertical element not a quarter wavelength on 20 meters for example, not being 16’11.5” (like the Dipole)?
1. ANSWER: The Vertical is not a quarter wavelength because the Vertical element and Counterpoise wire have different Q values, which include O.D. and resistive values. This is not the case for the Dipole because both elements have identical Q values.
Q VALUE NOTE – O.D. of wire 2mm vs a much larger O.D. for the telescopic element AND resistive values being stranded copper-clad steel wiring vs 304 stainless steel.
2. QUESTION: How were the counterpoise lengths determined, were they calculated?
2. ANSWER: Counterpoise lengths were determined in the real world by using multiple analyzers. Determining (rather than Calculating) the Counterpoise lengths is best accomplished using an analyzer due to the difference in the Q values, especially when it changes due to varying ground conditions from site-to-site. So, an analyzer is the best option when making adjustments to the counterpoise lengths, whether it be for an end user or us as the manufacturer of the HexTenna system.
3. QUESTION: Was the 6 Meter Vertical element length left off the chart on purpose?
3. ANSWER: 6 Meters was left off the chart because we could not get it to resonate using any of our analyzers.
4. QUESTION: What happens if the Counterpoise wire not long enough to reach the ground or if it is too long?
4. ANSWER: Whether the Counterpoise wire is touching the ground or not, and when it is required for resonance, per Chart 1 in the Hextenna_Technical_Guide, you will attach the Counterpoise for the Vertical to the location on the HexTenna hub marked Counterpoise. You will then only need to roll the Counterpoise wire out till resonance is shown on your analyzer for whatever angle you have it deployed at. Simply using the Velcro strip to secure the Counterpoise wire into a coil is sufficient for any of the deployed lengths.
