[Elecraft] Really OT: Inside-the-vehicle HF antennas (possible bonus points)

[Wayne Burdick]

I’m dealing with one of the last unsolved problems in amateur radio: how to operate HF mobile without an antenna. At least not one that, according to some vehicle co-owners/spouses, would defile your new sedan.

For 10 bonus points that have only philosophical value, your challenge is to create an invisible mobile antenna and actually make a QSO on it. For practical purposes (i.e., not frying the car or passengers) let’s say the maximum power level is 10 watts. The bands of interest are 40-10 meters.

Here are some ideas I’m considering:

- mag loop in the rear window
- thin wire loop on a roof rack 
- gamma match to the entire roof
- surface acoustic waves
- prayer

Other ideas?

Yes, I know this violates the laws of physics and bioethics. And I fully expect the car to generate debilitating levels of RFI. But isn’t this the least you’d expect from an unsolved problem? 

Thanks in advance,
