PST2-4080C
A compact dual-band wire antenna, designed for installation in confined spaces. Full-size elements for 40m, with almost full band coverage. The loading coils allow use on 80m, although in a fairly narrow slice of about 30 KHz. For optimal operation, it is recommended to mount it at least 5-6m from the ground in an inverted V configuration, with an opening of about 100-110 degrees. The antenna is pre-tuned to operate in the center of both bands, and like all dipoles, it is affected by environmental conditions, so it may be necessary to find the best operating point with several attempts. The center dipole also includes a 1:1 ferrite balun.
