VY1MK Mark, 2m and 70 cm

Oct 2016 - 2 X dual band and 3 VHF jpoles up. Single coax and loads up almost perfect on both 144/440

VY1GP George, Flag Pole Antenna

Oct 2016 - References: Youtube - Flag Pole Antenna Project, Force 12 flag pole antenna - check the RF charts and video.
Constructed of 2 10-foot alumiumn downspout, 1 piece of plastic downspout (Home Harware) and a few bits of coax, wire and screws. SGC tuner is at the base of the antenna for 80-10m.

VY1MK Mark, NPOTA

Sept 2016 Mark built a new multi-band antenna for activation of National Parks on the Air (NOTA) at the Summit on the US/Can border. His antenna design comprised a home-brew buddipole and two wire dipoles.

VY1YU Yuuri, 2m J-pole

Homebrew 2m J-pole [buddi-pole components] (click on small pictures)

Tried to build a bottom-fed J-type antenna for 2m, using various buddipole elements, but the shortest elements are just a bit to long to get it to be resonant on the 2m band. So I designed my own pseudo-J antenna with a parasitic element that helps shift the feedpoint impedance to where I want it (near 50 Ohm resistive).

Three pictures show the mechanical structure and three show the results of a sweep: you can see that the SWR is pretty low across the whole of the 2m band. The three sweep images differ only in where I marked apparent antenna resonances (two of which fall inside the band).
