Flower Pot Antenna Dual Band

Membuat antenna dipole 27 mhz 28 mhz duration.

Flower pot antenna dual band. Experimental dual band high gain flower pot antenna. Operation on the third harmonic is achieved by using a sleeve technique so as to form quarter wave phasing sections at the higher frequency to end feed two half waves in phase at the third harmonic. Experimental dbhgfp antenna a challenge laid down by m7mnp thanks mav.

Higher gain is achieved by adding an additional half wave element at the fundamental frequency 2m coupled by a half wave phasing line to drive both half waves in phase. The half wave 2m version of the flower pot antenna is easily modified to a dual band antenna for operation on a band that is the approximate third harmonic of the fundamental resonance. Theoretically this should provide an antenna gain of 3dbd at 2m.

Anyway the credit here must go to vk2zoi. 2m 70cm dual band half wave flower pot antenna. I think it s possible to realize the same kind of antenna for.

The basic half wave version of the flower pot antenna can be readily modified to dual band the antenna for operation on a band that is the approximate third harmonic of the fundamental resonance. I realized a dual band antenna for 20 and 10 meters band using a flowerpot few meters of rg58 cable and a variable capacitor. Antena jest tania i prosta w produkcji.
