Essenzialmente, questa e' una singola antenna verticale a 1/4 d'onda con radiali a terra, complimentata da una coppia di verticali parassiti
7 band semi vertical trap antenna
The vertical section of their antenna is listed as 32'-6" high with a 7.00 MHz trap mounted at the top followed by 27'-6" of horizontal wire for 80m
1/4 Wave HF Multiband Vertical for 40 - 10 Meters
It consists of 3 sections of thick wall PVC connected together and may be self supporting
80/40m Vertical
The HF2, is about 30ft long, and has an L/C band switching arrangement near the base. This L/C circuit consists of two coils in series

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
