Many of the compact commercial verticals such as the JPC-12 antenna utilize a ground spike to support the antenna. It is very easy to pack up your vertical and leave the spike behind. My solution is to tie a foot of brightly coloured plastic marker tape around the spike near the top.
Attaching wire antennas to a fibreglass mast for portable operation can be a challenge and it often results in the tip of the mast eventually getting broken. Here is a solution that takes the strain off the fragile tip section of the mast.
As part of building a my first station suitable for “tail-gate” or vehicle-based POTA activations, the consideration of which antenna provided the greatest flexibility led me to consider the JPC-12, which I acquired from DX Canada.
For the OVMRC POTA-in-the-Park event at Hogs back park (# VE-1596) local operators gathered in less than perfect weather to enjoy some good RF propagation. While Norm VE3LC activated the park, 6 operating positions were set up and 18 people participated.
