​This is short description of my SOTA antenna – Linked dipole. It is common dipole with jumpers, so you can choose band. See pictures below.

Wire is copper 0,5mm2, center part and insulators made of plastic and jumpers are 2mm banana plug. Dimensions come from simulations in K6STI software and in practice are the same. It supposed invered-vee shape, center about 8m high and thin wire but those parameters are not critical.  Minimums SWR are about 1.2 and should be in bands. Listed length for 7 MHz is for CW, if you prefer SSB cut last sections approx. 14 cm. Other bands have good SWR in whole band.

Dipole should have BALUN in feedpoint but I think it is not necessary for SOTA use. Coax cable is thin and light RG-174.
