Hi guys I want to get the dbs itelite antenna (non-boosted) with the clean install kit. I fly mainly in the city. Using wind surfers right now I get about 4000-5000ft in dense urban area's. I'd like to be able to go up to maybe 6000-7000ft. For those who have the ITElite how do they compare to the wind surfers?. Or should I just save up for the boosted ITElite package. Thanks!
