It's easy to make a half wave dipole but hard to make a portable antenna that's appreciably better than one. A dipole's main limitation (if fed with coax) is that it (generally) gauge stranded wire (minimum 50 feet or ½ wavelength at the lowest frequency you will use), plus extra for a counterpoise. If you will be running QRP only, you can use wire as small as 22 gauge. You can also get a loading call for 14 meters but that’s how compact is that. So we’re talking about the short whip and the short loaded whips. As I say you don’t need an antenna tuner, because it’s easier and it’s more immediate. And my experience is if you need an 80 you should resonate the antenna when you’re out operating portable. If you want good performance on a single band and are near salt water it's hard to go past a vertically polarised single element delta loop. These videos show what's involved. frequency. But unlike the delta loop it needs two supports. These don't need to be as tall as the single support for the delta loop. I could have made the loop a square

The antenna is extendable to 12 feet (3.7m), and collapses down to 12 inches (30 cm). The tripod collapses down to 25 inches (64 cm) and the go bag size is 13 inchesx9 inchesx3.5 inches (33x23x9 cm). The power rating is 500W SSB, 300W CW/DATA. Overall The major point about aluminum is the relative ease of nesting one inside the other to yield a long antenna from short components. As one of the goals of this Asymmetrical Hatted Vertical Dipole is portability, this had instant appeal. The IC-705 uses the RF direct sampling method, which greatly reduces distortion. The high speed/high resolution real-time spectrum scope and waterfall display are incorporated in a compact design for the first time in this class. Other tests reveal the ground does have some effect and broadens the bandwidth from 7% to about 10%. That’s clearly loss in the soil and not a surprise. These measurements were made in haste as I was marking the various tube settings with a sharpie. The good news is I could easily, very very easily, achieve close to 1:1 if I spent more time. A Return Loss of 25 dB or more is well within reach of this antenna topology.MFJ-2289 If you're headed for the hills or off to the shore, MFJ's BigEAR portable HF antenna sets a new standard for toughness, simplicity, and QSO grabbing! Efficiency is the key to launching a big signal in remote areas and BigEAR™ does it so well that you might forget you left home, The smallest and second most efficient antenna is the magnetic Alpha Loop. It requires you to turn a knob on the antenna to tune when changing bands. These first two antennas are very effective for even low power operations. This is because they have a higher efficiency Q rating. Having a higher Q rating means an antenna has a narrower bandwidth. the same antenna can be listed twice, depending on the operating frequency. For example a wire vertical 10 metres long is a half wavelength on 14 MHz but only a quarter wavelength As ham radio enthusiasts, we recognize that portable operation can be an enjoyable experience, although it comes with its unique set of challenges. Recently, I found myself in a conversation with a newly licensed ham, who posed the age-old question: “What’s the best HF antenna for portable operation?” This question isn’t easy to answer, as it hinges on various factors, such as your radio’s purpose, the required frequency coverage, and your proximity to potential signal-obstructing obstacles (yes, trees, we mean you!). But fear not, we’ll work together to find the ideal portable HF vertical antenna to meet your needs.

other bands without needing to trim the antenna wire. Of course it then ceases to be a half wavelength on these other bands; on 7 MHz it's a 1/4 wavelength, 10 MHz 1/3 wavelength, You may need to change the dimensions slightly. To do so start with optimising the length of the inner portion (for 14 MHz) with the clips for the other sections open. Then optimise for 10 MHz, I have never once built a home-brew aluminum antenna. Readers of this blog will attest to my affection for antennas made from locally available copper. Now was as good a time as any to make this antenna the traditional way. I’ve found that often my antenna won’t work. If I don’t have an external tuner, then the wire will end up being too short and this makes it difficult to get good reception. To avoid these problems in future,I want something with simple compact design like whip antennas which are resonant when you’re right next them without any need for an earth or ground plane attached – unless one has their own device doing so job already! The easiest way is simply to run out a length of wire along the ground, which is connected to the earth side. And that acts as a ground plane. That is absolutely essential. And don’t ever try to operate with a wit without having a ground connection or preferably with a wire or sort of counter-voice connection. It just won’t work. I decided to price out the aluminum for a home brew portable HF antenna. The cost savings was just enough to speed things along.as the support poles do not need to be as tall. A Moxon takes longer to erect than some of the simpler antennas described. You may need to use two masts. Because Apologies to everyone. The absolutely essential feedline choke is not an inherent part of the antenna design. Schiller’s Bravo and this design assume you will provide this as part of the feed system.
