A few comments from the many satisfied customers using the G4TPH Portable Magloops:
"i have one of your ml40 Magloops and i would like to take this opportunity to tell any prospective buyers that i have worked most of europe, russia, east and west coasts of north america and a few countries in south america with this antenna indoors in a first floor bedroom! this was exclusively on psk mode and only on 20w! i have no connection to the maker of the antenna (G4TPH). just thought i'd pass on my experiences of using this antenna."
thanks Ian G1WEV
Dear g4tph,

Hi Tom
I have now had time to test the loop antenna, and on 20m with 15W I worked Italy, Spain on PSK31
Amazing result considering that the loop is indoors around the window.Much stronger sigs and less noise than my verticals.Can I run 20W with this antenna? What do you think the max it can handle would be ? Also the clarity of SSB is the best so far.I will let you know more shortly. Well done for a great solution to no antenna space .
regards es 73
