Seen this truck twice already. I parked next to it the other night and got some some pics to share here to see what you guys think!
Maybe this guy is on this forum since he's a radio guy and can give us more insight to his antenna.
This truck has another set of this same antenna on the other side so I assume it's a co- phased setup.
What I see is 2 equal length horizontal elements with loading coils with cap hats on each element. There is also a shortened vertical element with the same length cap hat on it. The ground radials at the end which are far to short to be really effective but at least they are mounted to a non-conductive mast and not on the hot side of the antenna like many of those so-called cheap ground plane radial kits. The antenna does has some serious looking mounting brackets which is good due to the weight and wind loading.
From what I see, this wouldn't be a very good local or running down the highway antenna due to the horizontal elements. Typically mobile antennas are vertical so this is the wrong polarization to be effective against other mobile antennas. But, that antennas vertical element may skew the signal in an angled V pattern creating some kind of dual polarization.
The 2 elements close together and being equal length don't seem to be effective at creating a "beam antenna" not to mention what the same antenna on the other side is going to effect one to the other.
However, this is one of the more fascinating mobile antennas I have seen in recent years!
