Dipole 15,12,10mtr

Multi-Band Dipole 15m,12m,10m

Here's a simple multi-band rotary dipole for 15,12,10mtr amateur bands, it is based on open sleeve resonator design and made from 13mm aluminium tube.The main radiating element is a split dipole cut for 15mtr with a second 1/2 wave parasitic element cut for 12mtr mounted 100mm above and a third 1/2 wave parasitic element cut for 10mtr mounted 100mm below the main radiator.

The antenna was modeled in mmana-gal, the screenshot below shows the current distribution on the three band at 8.8 mtr above ground.

Current distribution 21.200 Mhz

Current distribution 24.940 Mhz

Current distribution 28.500 Mhz
