Antennas : 160M
  • Wire antennas for the low bands - Experiments by G8JNJ on wire antennas for low bands. Based on these tests, conclude that for multiband (160 to 6m) operation, in a restricted area it is very difficult to beat a G5RV, especially the ZS6BK version.

Antennas : 40M : 40 meter Vertical Antennas
  • 40m Vertical End-Fed Antenna - A quarter wave vertical end-fed antenna for the 40 meters band. As all vertical antennas, also this aerial requires a good earthing system. In this project the ground is composed by twelve 4, wires buried in the lawn by using a spade to create a slit to drop the wire into.

Antennas : Dipole
  • Inverted V - Described is a simple inverted-V antenna which, when used with a balanced ATU, can be used on all the main Radio Amateur HF bands (80, 40, 20, 15 and 10m). The cental support is made in such a way that the wire can be coiled up for storage when the antenna is taken down.

  • Speaker Wire Doublet Antenna - A portable wire antenna for the HF bands, made with a common speaker wire. In its natural form, the speaker wire acts as parallel feed line coming up to the bottom of the PVC feed point. From there, it's split into two wires, one heading out each side of the PVC tee.

Antennas : Receiving
  • Double Half-Delta Loop RX Antenna - This wire antenna was developed to offer for a small, low-band, ground independent directional receiving antenna, it requires only two support poles. It is basically composed by two interconnected half delta loops and is better than a single flag or EWE, and almost as good as two phased EWE in the same space.

  • Long Wire Antenna for portable operations - 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.

Technical Reference : Vector Network Analyzer
  • miniVNA PRO Modifications - The mini Radio Solutions miniVNA PRO is the only affordable vector network analyser (VNA) I know of that offers remote wireless operation. This is very interesting because it allows to measure the input impedance of HF antennas installed at height without having to deal with coax cable lengths, baluns nor common mode suppression chokes. However, to render the miniVNA PRO truly field proof, it requires a number of significant modifications.
