Michael, Some good suggestions from others.
QRPMEkits has a nice small ant tuner as a kit if you decide to use one.
I have used both a full sized dipole as inverted Vee- requires at least 40 foot each side of the center support -but is most efficient and a reduced length of 50 feet and loading coils at 50 to 60 percent of distance toward the end from the center. Both are efficient.
Short run of RG 174(30 feet) or longer run of RG58C(40 to 50 feet) will do well for feed line. Look on internet for program "LODIPOLE" . It will help design the loaded dipole and the coils needed.
100 feet of nylon rope can be used to pull it up into a tree.
For a center mast, a jacpole or at least a 7 meter telescoping pole will do. SOTA in England has a nice telescoping pole.
Also 4 or 5 telescoping sections of PVC pipe can make a center mast. Length of each section as needed for easy transport. I have my mast in 10 feet(3 meter) lengths of 1 inch and 1/2 inch PVC and it works well for a 20 foot mast. Overlap 6 inches and I use adj clamp for portable setup with 3 inch slits in the end of the 1 inch PVC. Tie it to what ever support is available
I also use two as home base masts for ends of a 44 foot inv vee fed with 300 ohm line. The center is a 10 meter bamboo pole.
