2014 VPA

Poles are 9.6m in length. Rear reflector is mild helically wound to achieve extra 40cms
VPA beaming North West
Location of house -vs- Atlantic
Looking East from the front of the array
Obligatory evening photo of antennas
Acom showing great SWR and 400w CW
MFJ.. never seen such a good SWR (not actually a sign of efficiency)
Construction of feepoint base showing radials
Feedpoint and ground radial assembly
Parasitic feedpoints, showing temporary connector to measure SWR
Element can't touch the guying point for fear of flash-over
Guying system
3d-plot from MMANA
Comparison plots using MMANA modelling s/w
