With the view to establish a quick and easy multi-band antenna deployment for portable and camping operations a simple long wire antenna with an earth or earth plus counterpoise arrangement with a 9:1 voltage unun including a tuner or simply with a tuner is one possible solution. With the 9:1 voltage unun and wire lengths suggested in the below tables the antenna should present non extreme impedances for all HF amateur band frequencies. This page is far from complete and represents the ongoing investigation into this type of antenna. Experiments to date seem to have raised more questions than obvious answers.

The HA8TKS VHF DXCluster is an essential online resource for amateur radio operators focusing on VHF and higher frequencies. This platform provides real-time information on DX spots, allowing users to track and engage in two-way radio communications effectively. The integrated map mash-up feature enhances the user experience by visually displaying the locations of DX stations, making it easier for operators to plan their contacts and optimize their antenna setups based on geographical data. In addition to the DXCluster functionality, the site offers various HAM tools, including a QRB calculator, which helps operators determine the distance to DX stations based on Maidenhead grid locators. The platform supports multiple modes of operation, including CW, SSB, RTTY, and digital modes like FT8 and JT65. With a user-friendly interface and comprehensive data, the HA8TKS VHF DXCluster is a valuable asset for both novice and experienced operators looking to enhance their DXing and contesting activities.
