That's like a beam antenna, the last elements are the reflector. Your body was acting like a reflector since u were close to the antenna. I usually don't get too concerned about resistance readings on my MFJ analyzer. They say the 1/4 wave antenna has an impedance of around 32 - 36 ohms. So if u do the math 50/36 = 1.38 or 1.4 for swr reading. Its the reflected power or reactance to be concerned with. Ridgeline can correct me if I'm wrong.
antenna length?

Quote: ..."I just found it odd how i ha to tilt my meter the same as my ant to get the higher reading."..
Could this be explained by the polarization factor: the mismatch characteristics of vertical antennas interacting with horizontal antennas? -
That's a good possibility. I think the main reason is because there is no metal under or by the antenna to act as a counter pois (ground plane) to electrically make up the other half of the antenna .... kind of. I give these guys kudos for all the time, research, and $$$'s spent trying to make the antenna work with these new fiber glass trucks.

Just to clarify something, when you are standing there with a fs meter in hand, your body acts like a capacitor and this changes the reaction with the meter and the antenna of the meter. When I did the cascadia tests, I used fs sensors that were fixed and grounded to give accurate readings.
-
Ah yes, I didn't even think about your body acting like a capacitor. That makes sense, I was thinking it had something to do with the counterpoise of the vehicle.

The triple X is being built for Jason.

In reality there is no such thing as a counterpoise in a mobile application, it can not happen because there is earth ground involved.bored silly Thanks this.

Naw bored silly has one as well..

I was
I was just foolin around in a trk stop..I was cleaning out my closet and saw it in the back... -
My r is 57 on 26965 and my x was 6...27185 the r is 63 and x is 0 and finally on 27405 r = 71 and x at 0..Thought yhe r ment resistance not reactance..Either way its to high..Ill have to clean up my mounts connections and see it that lowers it any..
