This Page Covers 1. Inverted "V" Dipole 3. Inverted "U" Dipole. It's possible, however, to "fit" a full-length half-wave dipole in less horizontal space, while retaining most, if not all the advantages of the "classic dipole" described elsewhere on this site. See Antenna Section Contents in right hand column. Below are some of the possible configurations. One of them actually has a slight performance edge for DX over the horizontal dipole! The half-wave HF antennas described below do not impose the compromises of inductively "loaded" antennas using coils which are less efficient and have narrower useful bandwidth.

High voltage is present at the ends of half-wave dipole antennas when transmitting. The ends of the following antennas are lower above ground than normal! Take all necessary precautions to prevent anyone from coming in contact with your antenna!

This ham radio HF antenna needs only one tall support and takes less horizontal space than if it were to be installed horizontally. One end of the dipole is tied to the top of a tree or other tall support. The other end slopes down at a convenient angle. The radiation pattern will be almost omnidirectional You will find more information on the many forms of slopers here. NOTE : Don't have enough space for a full half-wave sloper on or 80 meters?

Don't give up! The inverted "V" or "U" configurations offer an excellent solution for restricted spaces. The inverted "V" dipole configuration is also a space saver!

If you feed this antenna directly with a coax without a balun at the antenna feed pointyou will definitely need to insert two common mode RF chokes in the transmission line. These are needed to " choke off " unwanted RF currents that will be induced by the radiating legs of the antenna, onto the transmission coaxial shield.

A vertical HF antenna offers many advantages—an omnidirectional signal collector and easy to install radiator are two of the biggest. HF verticals are versatile, and can deliver both multiband and monoband performance.

When used in a multi-vertical array, verticals can even provide low-band directivity. Verticals are specifically advantageous because their superior low-angle pattern promotes better long-range DXing. The packages include industry-leading instructions and technical support. Antennas are the most important tool in a successful radio station.

Things can get pretty much technical when you are looking to buy anything related to radio. We tried to keep things simple so that even new radio enthusiasts can understand. Most of these antennas are portable and can be carried to new places.

So, you get a bit of flexibility with them. The antenna is fully collapsible. It can be stretched from just 12 inches to 12ft. And the tripod can also be collapsed to 24 inches size. However, to access the lower ends of the HF bands from 3. Tuning is very easy in this antenna, thanks to the aircraft-grade aluminum tubular slide and military-grade slip connections. Apart from the antenna whip and tripod, you also get a radial set, ground mount, SWR ruler and a portable carrying bag.

The portability and the ability to communicate on HF and VHF bands is what makes the antenna worth buying. For HF, it operates on 3.

On the higher end, it covers 7 to 30 MHZ.

But for 2m, you will have to use an external adapter like the MC2 Superplexer. The antenna collapses from 7ft to 12 inches. And with an overall weight of 5 pounds, you can carry this kit anywhere you go. We really loved the SuperMount clamp which you can use to attach the antenna to virtually anything from fences to plastic pipes. The best performance of this antenna can be found on 20M and above.

The performance is similar to the large vertical HFs that are more expensive. If you want better performance than the MP1 we reviewed earlier, you should definitely get this one. However, it might be a bit on the expensive side. So, the price should be a factor here.Description Electrically balanced passive loop design with low loss RF transformer to cancel the responses to electric fields.

Ideal for noisy environments where electric-field sensors like the mini-whip antennas are impracticable. High Performance DX when used with a low noise preamplifier. High quality 2 meters approx. We came up with the YouLoop, a Loop you can build by Yourself. The rest of the turns run inside the shield.

This construction is electrically balanced for large wave wavelengths, ie. This helps cancelling the electric noise at the lower bands, exactly where most of the electric noise energy is concentrated. To preserve this electric balance from alteration by the transmission line, a low loss miniature BALUN is used.

The following diagrams illustrate conceptual architecture described above. The more turns, the higher gain at the lower frequencies. Note that to preserve the electric balance, the number of turns increases by increments of two. Another interesting aspect of this two-turns coax build is its response in VHF. Actually, the feed point of the folded dipole is on the top and the actual legs are composed of the coax ground. The gray curved line depicts the signal path in VHF, which should be familiar for most.

This pre-amplifier also allows using a loop with a much smaller diameter, which improves the portability. This could be the best option for those who do not want or cannot build the antenna from scratch.

The whole antenna can be assembled in a few seconds. Read more. If you need a copy, check A translatio These new nodes will be added in regions where there is a nee Unboxing the radio and taking a look at the menus. Ulrich Rohde, one of the founders of Rohde Posted date: March 21, in: Antenna.
