HF antenna for the truck

I swapped out antennas for the truck for this weekends camping trip.

I have several sets of MFJ type Hamstick antennas for the truck but frankly storing and changing them is bit of pain. I decided to try something similar to what I am using the car these days.

Wolf River Coil for 10-80m setup for 17m (The untapped coil has about 83uH of inductance)

I tried several different configurations

  1. Coil + 102" whip (base loaded) 12m-->80m
  2. Coil + 20" mast + 48" whip (base loaded) 15m-->75m
  3. Coil + 48" whip (base loaded) 10m-->60m
  4. 20" mast + coil + 48" whip (center loaded) 10m-->60m

Ultimately I am going to use option #4 for this weekend.  I did not like that load of the 102" whip moving around in the wind as it has quite a bit of mass compared to the other options.

 At 10m I am only using a couple of turns of inductance (top = 117) since it is almost a 1/4 wave tall

The configuration for the truck seemed quite a bit more complex to setup compared to with my car. The radio in the truck did not agree with the analyzer nearly as well as my experience doing this with my car. It took about 2.5 hours to setup the various configurations and then measure the results for each band.

This combination should work fine and I can quickly dissemble and store the components in the rear of my truck when they are not needed. With the tuning notes it should be pretty easy to change bands with a minimum amount of hassle.
