Over the last few years I've made numerous mobile designs using mostly 102" whips as the radiator. In my case I have a limit of 500 segment per model and the mobile body can require 1/2> of the 500 segments just for the body alone. So, I'm limited in making mobile models if the radiator is complicated by having a coil. Coils can require many wires and each wire has 1 or more segments. It all adds up, so I stick mainly with a simple whip antenna. Recently I checked several models I had made using various vehicle brands and shapes. I was surprise at the results when comparing the following mobile objects I had created when I added the radiator to the models. I was curious how different vehicles might compare. 1, the first model I ever made was a Blazer sent to me by Henry HDSP, a member on this forum. He is in the Netherlands. The model he sent me was a small vehicle that basically looks like a PU truck. It had no metal covering over the top of the back...like a real Blazer. The whip antenna is in the center of the cab and the feed point sits at 66" inches above the ground. The Blazer is 15' feet long overall and about 72" inches wide. 2. is a standard length PU Truck that is 15' feet long, with a 1/4 wave radiator in the center of the cab at 70" inches above ground. All models are set 72" inches wide. 3. is a Suburban with a 1/4 wave radiator that sits at 88" inches above the ground. It is 17.5' long. I made this particular mobile design based on a similar design created by The DB here on the forum. Here we made our mobile model object with far more wires, as noted. I'm just guessing, but I think DB made this model to see if a more complex mobile object, with more wires closer together, would result in a better and/or more accurate model. 4. the last model is my original SUV model that is about 15' feet long and 72" inches high above ground. The Suburban and the SUV models were positioned as close to the center, length-wise, as necessary to make the patterns...as symmetrical as possible from front to back. The PU Truck and the Blazer are in the very center of both cabs. The 102" whips for all models were adjusted to length at resonance. I will post these models after a few interested folks vote.
