NR, for best results stick it on the biggest bit of metal you can. Add four groundplanes, For bugging out, I used a Dv27 on a magmount stuck on an old Roses choccy tin. I drilled four holes equadistant around the tin and attached bolts with washer and nuts to hold the ground planes. Make the GPs from something like speaker wire, you only need one strand for each GP and you need to cut each one to 2.75 meters. Insulate the ends of the GPs with some insulation tape as GP can generate a bit of heat while transmitting. Hope thos helps
