Hi Magnus: Safety is the # 1 concern. It may be that if you can minimize the multipath problems having the GPS antenna near the roof is not a problem?
I'm starting to do some antenna related tests using the Polaris Guide (DAGR) GPS receiver, see: http://www.prc68.com/I/DAGR.shtml#GLS and scroll down for some zero base line tests of how well it does carrier phase distance and angle measurements (aka Gun Laying, Azimuth Determination, North Finding, Relative Survey Mode). Another test I'd like to do is measure multipath, but so far have not come up with a direct way to do it other that infer based on how poor/good some test result is. For example are the variations in the above tests due to multipath?
