ok everyone as i promised i finally finished my unscientific test of these two antenna's. basically the same length antenna except' the radio shack all terrain has a smaller base load. since the meter said the wilson was at 1.2 swr i adjusted the radio shack antenna as close as possible to 1.2 swr also.
I then mounted the radio shack antenna in a 5" mag mount' since the wilson is already mag mounted. so far as equal as i can make the two antennas.
the test. my son and i went out to interstate 10 in anahuac texas. from there to winnie texas is 20 miles of straight flat unobstructed highway. we set the radios on channel 20 dead center of the cb band. we mounted the radio shack antenna on top and in the middle of his pick-up cab. his radio a bone stock cobra 25. his instructions were to drive toward winnie untill i could no longer here him taking to me then stop. then remove the first antenna and replace it with the wilson and see if i could here him then.
well he got almost 8 miles when he died out. and even after changing to the wilson i still could not here him.
my conclusion of this test..... from a bone stock radio' i can't justify the expense of the wilson vs a 22 dollar radio shack antenna. at least from a transmit range. will it hear better?? i don't know i didn't test that. i'm sure where you will see a major difference and be able to justify the expence of the wilson with it's larger coil is if you have a radio pushing power.
