Captain Kilowatt, like I said above...I do depend on my models, but I also said (in bold above) I wasn't sure about the mobile objects I have been using. I was in error telling Joe he was right about the 1/4 wave installed on a mobile showing 72 ohms at the feed point.
My old antenna mentor always told me to look for about 1.40-1.50 SWR for a 102" whip installed on a mobile. He also told me if I got below this SWR then I would just be adding losses...just like you say above. I knew better, but I just messed up.
I have been working on my mobile objects to try and get one of them to respond by showing <>35 ohms at resonance, but nothing I've done so far has changed the high readings I've been getting. My models also do not produce a good Average Gain report results either, and when I first saw that is when these mobile objects started giving me concerns the models were not working right.
I have made a new model of a 14' foot Bronco mobile object so I could fill the model with more wires hoping to mimic a mobile vehicle body better, but that does not appear to help either. I filled out my model with 12" inch sections and made my wires 5.75" inches in diameter. This basically made the model a continuous exterior tin surface from top to bottom and from front to back and all the wires are connected together. I still don't see the match, using a 102" - 108" inch whip should show us.
I know The DB has made some of these mobile objects but I'm not sure if he has noticed this high impedance issue in his mobile models or not.
I recently asked him, in his thread on his new Explorer model, if his mobile object showed a good AG result or not, but I haven't heard from him yet. I don't think he would have miss such a glaring mistake in his mobile objects however.
I'm still working for a solution and thanks for helping me see the light.
