Subject: Field day, push-up masts and tower sections
 More times than not we end up running our field day operations from places
that are not quite the greatest locations for antennas.
 With this in mind the field day team must plan ahead by using the good ole
push-up mast. They are easy to tote to the site and set-up.
 Another item is the Rohn tower section. Mounted to a piece of plywood with a
mounting plate and guy lines to support the tower sections. A three section
tower is easy to assemble and tilt up with just a few amateurs.
 Add a mast and an antenna and up it goes.
 Looking at the emergency aspect of operation,a tower maybe a bit tough to
cart into a disaster area where the push-up mast would prove a better choice.
 The mast can be secured at the bottom using a spare tire and clamp/flange.
 Guying the mast is a must.
 The mast can be stored in a 4-in PVC pipe with screw on caps as discussed
earlier. Handles can be attached for ease of carry.
 Another concept is the crank-up tower mounted to the bumper of a pick-up or
van. The tower is slid back to the half way point and then tilted up.
 A step ladder allows the attachment of an antenna or used for tuning.
 Also this set-up allows the amateurs to attach the antenna before the tower
is raised when using a whip,wire antenna,or aluminum dipole antenna.

 I hope some of this postings have helped you with concepts used during field
day and in emergency operations.
 See you this field day from Cape Canaveral Air Force Station operating
as K4FD.
