The legend reveals the vertical height above the radial “H” and radial spoke length “R” dimensions resulting in each SWR plot. These are also in the KX4O-000049 Drawing.
When opting for QRP, you might want to use an end-fed half-wave resonant wire with a suitable matching transformer. If building your own antenna isn’t appealing, there are commercial options available, such as those made by Vibro Plex in the USA. They offer a full-size 40-meter-long antenna or a shorter Audible version that covers four bands: 20, 14, and 10 meters. Both of these options are suitable for the best portable ham radio setup. AlexLoop Portable HF Loop Antenna was invented, patented and introduced to the ham market by Alex Grimberg, PY1AHD, in 2007. Tried a half-square and liked it? Want even more low-angle DX gain concentrated in narrower bidirectional lobes? Don't have very tall poles Also offered is the convenience of switching between popular bands without twiddling an antenna coupler. The portable HF operating revolution brought about by the AlexLoop has spawned many imitators but none has reproduced the efficiency, portability and usability of the AlexLoop.

Want something that doubles as an end-fed half wavelength on 7 MHz? The good news is that you can get half-square type DX performance with just critical (approximately 22m radiating element plus a small counterpoise of 2 or 3 metres) for coverage of most HF bands 7 MHz and up with
I switched between them to do comparisons. Which one is consistently better? Watch the first video below and find out!
1. Super Antenna MP1LXMAX Deluxe Tripod – Top-of-the-Line Setup
typically from about 0.7 to 1.5 times the design frequency. Better results would have been possible if the antenna was direclty over the water shown in the video. Another good antenna for good DX performance near salt water is the vertically polarised rectangular loop. Like the delta loop it's a full wavelength perimeter on its design The best Ham Radio equipment for operators who demand top performance comes from Super Antenna brand. Operators will never be disappointed with the output of their transmission and reception! The above Moxon is a bit unwieldy for short-term portable operating. Wire elements can flap around in the wind and the critical coupling means that performance can vary.
Here are some HF and VHF antennas that will work with the Icom -705 along with the Nevada RC-105 antenna mount. The IC-705 is not supplied with an antenna as standard. a small coupler. I typically support it on a telescoping 9m pole and configure the wire so it looks like an inverted-vee (with the transceiver
In Conclusion
Alex has been an active ham for over 50 years and especially enjoys portable outdoor operation on HF bands. Sometimes you're desperate to get on air. You leave that all-important antenna wire at home. Or you feel like doing things the 'hard way'. Each AlexLoop is completely hand-crafted by Alex himself from the first screw to the final test. In 12 years on the market, the AlexLoop has become the most popular portable magnetic loop antenna in the world and has been considered the gold standard of magnetic loop antennas. They deal with aluminum tubing in a big way. I love my 43 foot antenna from them. It was a natural first place to go for a supply of antenna components.
