Horsefeathers. A 2:1 VSWR transmits 90% of the applied power. A 3:1 VSWR
transmits 75% of the applied power. Have you actually ever MEASURED a commercial aircraft band antenna from bandedge to bandedge as installed on an aircraft? Jim (Steve Roberts) shared these priceless pearls of wisdom: -find a ham radio operator in your area with a VHF capable SWR meter -(or just order a 2 meter swr meter from AES) if the SWR (standing -wave ratio) is greater then 2:1 then the antenna is not well enough -matched for even casual use.
