Thank you BoxCar,
I fully understand the height-factor but I'm thinking the trade-off of indoor vs outdoor would favor outside, on a metal patio table. Even though it would be a "table height," either would out-perform an indoor installation. Your thoughts ?
The beauty of purchasing both is that I could use the Tram on the roof of my Explorer (except for entering my garage) and the Slim Jim while camping or traveling...indoors or outdoors. The dBi gain of the Tram should out-perform the "unity gain" of the 1/4 wave on the Explorer roof.
Again, thoughts ?
