Sounds like you know your way around. Likewise I refused to cut up my 2006 for the same reason, however it did do very well at mil air. Always wanted to add some foil to its insides to block rf, shame they didn't make metal cases for it like they did with the 2004. Lol still have all the Bill Cheek scanner mod books sitting here, have to look them over. Likewise I need to get some antennae for dedicated mil air, a turnstyle for the sats and a discone cut for 220 to 400. I've also considered a off center fed vertical dipole for 220/400 as they have low swr every other MHz when designed for hf, perhaps even better bandwidth at uhf and are less fiddly to build than a discone, however it's not too hard to cut down the typical v/uhf discone for the band in question. Also been prodding a manufacturer I know to roll out a 220 to 400 bandpass filter that should help in high power v/uhf signal areas
