3.5 MHz – 54 MHz Portable Amateur Radio Antenna
The
HFp
Antenna
The HFp design provides a highly efficient antenna design in an extremely portable
package — the entire package weighs just over 2 pounds (1 kg). The antenna is highly
configurable, and, with the 80 Meter Coil, covers all the Amateur bands from 80M to 6M
(as well as most frequencies in between). Typical setup time is about 5 minutes.
The full 80 Meter band is covered by the HFp in overlapping segments, as seen in the
following table. Typical operating bandwidth for each configuration is about 75 -
80KHz.
The element configurations for the different tuning segments are shown in the 80 Meter
Configuration table, shown next. Element 1 is always the bottom element, attached to the
base insulator.

The radials should be extended to their maximum length for all 80M configurations.
The top Pull-Out-Whip should be extended to its maximum length for the 80M
setups, and adjusted as needed.
Just remember that the whip doesn't have much
adjustment on 80 Meters, as seen in the table below.
