MA160V antennas feature a heavy-duty, high-Q copper loading coil plus a wide 100 in. The diagrams are redrawn from Bill Orr's book "W6SAI HF Antenna Handbook". In theory, topband is an easy band to get on. This allows tuned QRO operation without a remote tuner. And, in many cases, these antennas can be used on multiple bands. • Active Loop antennas can be small – 1 meter diameter – low noise • Various array type antennas are fairly large on 160M – low noise • Use other band dipole for 160M receive – cut down noise • RX antennas are usually directive • Use TX antenna if that’s all you have • Any antenna is better than no antenna! The last series of compact 160 meter antennas were not that satisfactory. Updated 02/03/2021. It is even more difficult to build efficient antenna if you are limited by small gardens and irritating neighbours.

Hawker. Luckily, there is an easy, relatively compact and better performance 160 meter antenna design available, created by Rudy Severns N6LF ("Another Way to Look at Vertical Antennas), described in practical notes on John Tait's Antennae for the Low Bands page. It minimizes the real-estate needed for an array of any spacing. Simple Receiving Antennas When you first start out on 160m, you™ll probably use your transmit antenna for receive. vertical antenna, made from three 10 ft. This antenna is designed for stations having a difficult time putting a decent signal on 160M from small or CC&R'd lots. 73 Magazine 1970-2002. More Antenna Classics - C. A magnetic loop is an extremely high-Q antenna with a very tight bandwidth (think ~5kHz on the 160m band), but they are tunable. But, I had to fit (squeeze) the 160M dipole inside the boundaries of my lot! So, I bent the rules and the antenna, somewhat! ;-) The result is a "hybrid" dipole or "ungrounded" vertical amateur radio antenna, depending on your point of view! The feed point is just outside my basement shack window, about one meter (3 feet) above ground. The First thing I would do is get as much metal and earth wires under the grass in the small garden zig zag them if you need to but do cross them over My SWR is about 2:1 to 3. The antenna. There's the Marconi, End-Fed, Inverted-L, etc. Balun Waterproof Shortwave Antenna 160m-6m 1. Below are several antenna setups that are intended for 160 Meter operation. Amateur Radio Techniques - P. An Inverted “V” or Dipole is gargantuan, 246 feet long. Here is a drawing above showing the 80/160m antenna. Antenna experimentation is sure lots of fun! For the naysayers out there, like K9MHZ--why don't you cut Pete some slack? Feb 3, 2021 · 160 Metre Antenna for small gardens. If you want to try to use this antenna on other HF bands anyway, you will need to use a wide range antenna tuner to handle the unpredictably high VSWR values.
