The goal, One Antenna, 10 Bands, 10 - 12 - 15 - 17 - 20 - 30 - 40 - 60 - 80 - 160 Meter.
Upon initial testing, very good results.
A Stealthy HF Coat Hanger Antenna
No, this is not about some cute antenna that's about the size of an oatmeal box and runs at 100% efficiency from 160 all the way up to 10 meters (and 6 meters if you leave the oats). In fact, there's nothing new on this page. It's just about a very common HF antenna that I recently built.
First an eyes check. Do you see an antenna in this picture?
9 band vertical HF antenna
Simple vertical radiator with a not so simple matching box. No traps, no tuner required.
160-10M Sturba Curtain
This design will work all bands from Top Band to 10M using a tuner.
Skywire Loop Antenna
In we ham radio operators' continual quest for the perfect antenna system, we try some strange things at times, but often, the simplest is also the best. That is certainly the case with the basic "loop" antenna, an often misunderstood critter, but one that gives absolutely the most for each foot of wire of any antenna I have had occasion to play with.
First, let me reassure you that such an antenna does not necessarily take much room. One reason I went to one in the first place is because I didn't have room for a 260-foot-long dipole for 160 and I wanted to give the "top band" a try for the first time in my 45 years of being a ham. If you are talking 75 meters (and up if you want a multi-band antenna...more later on that), it's only about 65 feet on a side in a square arrangement
Short dipoles and verticals from DJ9RB
Basic design details for a number of different antennas from 160m to 40m
80/40m Vertical +160M at a push..!!
I have always admired the Butternut vertical antennae. They are very well built using good quality doorknob capacitors and nice airwound lowloss coils. Having had an HF2 for a while I decided to see if I could make a homebrew improved..?? version.
Double-L Antenna For 80/160
A popular misconception about vertical antennas for the low bands is that they must have elaborate ground systems. Here’s a vertical antenna for 80 and 160, fed with a single feed line that is simple, effective, and requires no ground system. You won’t beat the 4-squares, but you will hold your own against a grounded quarter wave with ridiculous amounts of copper in the ground.
A Multiband Vertical
I have to thank Con, DF4SA, of Spiderbeam for giving me the opportunity to inexpensively try their new 18m telescoping pole. I turned it into a great 160m through 30m antenna; as a bonus it makes a good tree surrogate to hang a 15m dipole from.
Antennae for the Low Bands..80 and 160m
On the higher bands the same antenna is usually used for both TX and RX . The Low Bands are different in that one good TX antenna is probably adequate. If the TX antenna is relatively inefficient we can compensate by using more power. But for RX we require antennae that have the very best signaltonoise ratio (SNR) that we can muster. It is also very advantageous if these antennae are directional. Sensitivity in the RX antenna is not really that important so long as the SNR is excellent.....A good low noise amplifier (preamp/LNA) can give us all the sensitivity that we need.
KE4UYP TopFed 1/4 Wave Linear Loaded Vertical For 80 and 160M
This is a vertically and horizontally polarized antenna the Linear loaded 1/4 wave length vertical radiator introduces very little loss. The over all radiation efficiency is high at 80% to 85%. Enhancing this vertical radiator is the 1/4 wavelength horzontally polarized radiator (counterpoise) Located at the feedpoint and note it is at the top of the antenna giving you an almost totally omnidirectional pattern of high wave angle horzontally polarized Radiation.
Gain=1DBi
300khz bandwidth under 2:1 SWR on 80m
100khz bandwidth under 2:1 SWR on 160m
You will be quite amazed with how well this antenna works on either 80 or 160 meters.
The Kite and Balloon Antenna Site
Kite and balloon lifted antennas for Top Band and higher from YB5AQB (Plus YI9CC and 9M2/G4VGO)
The INVERTED 'U' ANTENNA for 200 meters and down
Do you find it hard to get on 160 meters because of the antenna? This simple wire may be just what you need. It installs easily, needs no elaborate ground system, yet performs very well. A little ingenuity solves two connundrums at once - getting the current high in the air, and lowering the current (and hence losses) in a very simple ground system.
160m and 80m Coaxial Receiving Loops
W7AE built the first loop for 160m following plans laid out in the ARRL Antenna Handbook. Encouraged by the results I built one for 80m. I found that with a proper preamp such the Palomar series or Ameco's PT3 there was a significant lowering of noise but the signals that I was unable to hear on my sloper now were quite workable using the receiving loop. For the past several years we experimented with several different configurations including a circular and square loop. We found that the diamond configuration worked the best. The 80m version requires a preamp to bring the signal up to an acceptable quality.
The Battle Creek Special
2 versions of the Battle Creek Special (top band vertical)
First there is a wire version. The traps are make of coax cable as describe by W1FB.
The second version is a 'real' vertical make of tubes complete with a description of the traps.
Top loaded vertical for 160 meters
This is a 90 foot tall top loaded vertical for 160 meters. It is constructed from aluminum irrigation tubing and has four sets of four guys each. The top guys also serve to support the top load wires. It has a "temporary" wire stub about 68 feet long hung off the side to provide operation on 80 meters. More details are pictured below.
80/160m Small Receiving Loop
I live in an apartment complex with 980 units, all of which are outputting some electrical noise. This makes copy on the low bands very hard. A small receiving loop helps; it has very deep nulls and makes listening on 80 and 160 more pleasant.
