You can bend the wires in a half-wave dipole so that it takes up less space, with minimal loss of efficiency.It is advisable to get the ends of the antenna as high as possible, especially if children and animals are kept in the area around the antenna, as there are very high tensions on the ends of the antenna during transmission! In Norwegian
Simple 144 MHz 2 metre dipole for mounting on a telescopic fishing pole
Lightweight portable QRP 2m & 70cm half wave dipole for SOTA or an emergency antenna for the 2m and 70cm Go-box.
This log software sends current QSOs to TNXQSO.com server, receives from your TNXQSO.com server your current RDA, Locator, and RAFA, keeps real-time QSO statistics, support for working with CW macros by the COM port. It is not intended to be used as a generic ham radio logbook program, but as a companion of tnxqso service
