Terlin Antennas – getting SWR down
Dom (17-Jan-2017): Before heading off on a 2week trip to the (quite hot) Red Centre I was just doing a quick sweep of my HF antenna at lunchtime. Although I have a nice dip at 7060, it doesn’t go very low, about 1.65:1. This limits my BW on 40m a bit. Antenna Mounted on bullbar. Any […]
Flower Pot Antenna on a wire
Here is a very handy aerial for permanent and field day installations. We’ve used VK2ZOI Half-Wave Flower Pot Antenna’s design, however we’ve only used the UPVC conduit for the choke section. This gives us a 2m aerial on a wire. It can be raised by pulling from the top, typically with a rope over a […]
Ross Beaumont (VK2KRB) – Quadrant Antennas
Ross Beaumont (VK2KRB) has shared his report on a suitable antenna to provide quasi-omni-directional coverage in azimuth from an antenna that is light and simple enough for amateur use, and focussing specifically on Quadrant antennas: Quadrant Antennas
Three band end fed antenna
Geoff VK2TGO recently gave a lecture on an end fed antenna for 40-20-10m. This antenna is fed using a 9:1 unun, just under 13 metres of wire and a loading coil near one end. The antenna wire itself can be deployed in many ways: vertically, as an inverted V (with the feedpoint at one of the low […]

Recently, the club’s email reflector has been buzzing with discussion of the best wire for use in dipoles, both temporary and permanent installations. Many opinions were bandied back and forth, the details of which can be found in the reflector archives of YahooGroups under the subject line, “Dipole Wire”. Tim VK2BT offered some of the […]
