Dual Band Half-Wave Flower Pot Antenna; Single 5/8 Flower Pot Antenna; Double 5/8 Flower Pot Antenna;tional single band ribbon J-Pole design to dual-band operation. I will use the antenna design that I gave as an example: a 40 foot While fundamentally broadband in nature, the BCMA is nominally targeting the frequencies of 137 MHz and 255 MHz to address VHF/P dual-band. Cubical Quad Antenna Calculator-- From KD6DKS Cubical Quad Antenna Design-- from N6VNG Cubical Quadsfrom EI7BA . 5-Band, 1/2 wave rotatable dipole for 40/20/15/10/6 meters. The influence of different slot styles on the antenna performance is discussed. wb2lua. What separates this design from a vertical dipole is the method of feeding the half-wave element. You'll also find here many innovative new Accessories for hf/vhf portable antennas. 2 Two-element array 15 2
