Thank you Andrew! I had expected a stronger directional effect from the 2m whip, but your analysis lines up well with the QSO Map. The AX1 is not the best, but it is not a dummy load either. I guess even 5 watts of RF energy has to go somewhere. 😉

Ok, added the car, the wireframe model is really raw, but it should give you a better idea and... yes, the car has an influence on the pattern, just look at the attached pic which shows the radiation pattern on the 20m band

Brian,
Location is also important. I have a homebrew DS1-type antenna (6 foot whip and a coil at the base). I can make contacts here in the lower 48, but I couldn't even hear anything on it from Denali Park last month.

Mike, try this; open this mapping site

https://caltopo.com/map.html

center the map on your location, then right click the map and select "simulated view", that will allow you to see if there are "obstacles" toward a given direction ;)
