I have often thought of a dipole as a 1/4 wave with 1 radial... they really are rather similar. I have regularly loaded a 1/4 wave for 11m/10m and 20m and 40m against a vehicle. I have a metal to metal SO239 mount and vehicle panels fairly well bonded. In addition I run a bunch radials off at roughly 45 degrees and peg them down just for good measure.

I get something like 1.8:1 with no radials and once radials on it produces a better match to 1.2 /1.3:1 - I run the 10m wire for 40m up a 10m fishing rod. Technically I could drive so that is some mobile antenna, though obviously I would not want to do that.

It is a rather odd antenna including the vehicle and radials but it works pretty well.

It just made me question why a GPA is called a 1/4 wave and a dipole a 1/2 wave. I suppose you don't 100pct need the radial for the 1/4 wave and could use a ground pin if the ground was salt marsh or sea water.

The simplest of antennas can keep your mind going for months and years... still learning more and more about them and this thread is helping. It never ceases to amaze when they are well set up what is achievable with quite literally a piece of wire and favourable conditions... it seems nothing less than miraculous. For most antennas I have an inline coaxial ferrite choke patch lead then my feeder just to make the pattern what it can be without the influence of feeder.

[QUOTE="TheBlaster, post: 776049, member: 58745"] I have often thought of a dipole as a 1/4 wave with 1 radial... they really are rather similar. I have regularly loaded a 1/4 wave for 11m/10m and 20m and 40m against a vehicle. I have a metal to metal SO239 mount and vehicle panels fairly well bonded.
