ok ill be serious for a few. depending on antenna. but probly a good idea for any vertical antenna, is to isolate the antenna from the mast with a non metalic material. to keep the mast from radiating. example: fibreglass stick. to keep the mast from radiating and/or becoming part of the groundplane/counterpoise.

if its an unbalanced antenna such as the imax or maco 5/8. make or ad a choke balun to the feed point to keep the coax from radiating.

aswell as grounding everything else as metioned above.
