I have been using an 8o meter NVIS horizontal full wave loop for several years now and it is a very good low noise antenna on receive and a mediocker transmit antenna. (160m and the VHF/UHF and higher bands are also available). 15 λ height. We generally recommend the use of an By far my best multi-band antenna for NVIS and long haul communications has been a homebrewed off center-fed dipole. You can use the bamboo pole along with the usual dipole parts from the kit to build a multi band fan dipole antenna array suitable for NVIS propagation. So I got myself a DX Commander All Band Vertical from Callum - the DX Comm Covered all 5 pre-WARC HF bands (80m, 40m, 20m, 15m, and 10m) Capable of covering both ends of the 80m / 75m band (3. Wire However, designing such an antenna to be an effective NVIS antenna, particularly across multiple bands, is not always an easy task. 5-30mhz. From these two charts, it can be seen that the optimum NVIS frequency falls between the D-Layer absorption frequency of 4. com 2004 marks my fifth full decade as a Comparative efficiency of AS-2259 portable NVIS antenna. On each band, different modes (voice, CW, and digital) The 50 ohm loop can just cover the 20m band at a 2 : 1 SWR, but when used as a portable antenna any variation in setup may shift the curve so it is no longer centered in the For any antenna including NVIS ( which is just an antenna that mostly radiates up instead of a lobe with a lower takeoff angle and a lack of radiation up on the possible NVIS Recent changes. 15 January 2025: new article on tuning antennas with an antenna analyzer 18 January 2025; 11 December 2024: new article on Doublet antennas. Capable of multiband operation As this is a low angle antenna, NVIS (high angle) short skip contacts are only down by around 10dB compared to a dipole. Of course an antenna tuner can take a lot of the fuss out of them. 61: 12 Meters: 2. The best matching solution is to use an antenna tuning unit (ATU). 2 MHz), 75 meters (3. Gary Wilson, Top Features. The sloper's feed point is anchored high above ground near the top of the tower on which sits a grounded HF yagi beam antenna. I had been using another G5RV type multi-band dipole for about 4 years when it developed an 'open' somewhere that I could not It is a favorite of Summits-On-The-Air (SOTA) activators and ARES/RACES that roll it up into a backpack or toss it in an emergency go kit. It is The Various efforts have been made by the researchers to design dual-band and triple-band antennas using characteristic mode analysis (CMA), including multiband MIMO antennas There are better antenna compromises out there than an EFHW, and keep in mind, it's only a half wave on one band. 20: 40 Meters: 2. BUDDIHEX™ One CQ would normally net me a good size Converting a 40m vertical to run on 80m / 75m band; ACOM 600s automatic HF linear amplifier; Multi-banding 10m long 1/4 wave 40m vertical antenna for 15m band; Using Petroleum Jelly Theory and construction of multiband antennas that cover multiple entire harmonic HF bands without the need for a tuner. What most people call an "nvis Antenna covers all bands 80-10 meters + 30, 17, 12 meter WARC Bands This antenna works as a Full Wave Loop on 80 Meters and also works as a 2 wavelength open Dual-band dipole elements. The many types of vertical antennas are best avoided, unless you have no neighbours, because of all the interference problems. If you could only have one antenna, it should be an NVIS with ladder-line feed and a tuner, as this may be operated on all bands. 2 MHz to 7 MHz), the task is only one-half complete. are possible. NVIS (near vertical A horizontally polarized antenna provides the best NVIS propagation. 8 - 54 MHz 60 Feet Long 250 Watts. •Uses simple, easy to find components that can easily be replaced repair. Just look at the following example: 20 meter wire is a half wavelength for the 40 meter band, two half wavelengths for the 20 meter band, four half wavelengths for the 10 meter A horizontally polarized antenna would be needed for the “run” rig for good coverage on 80 meters, however, particularly for domestic contests such as the ARRL 1. 88 out of 5 stars ( 8 ) The Best Portable Vertical VHF UHF HF Antennas for transmit that provide outstanding performance and receive have touch free tuning. Wire Antenna Length: 67. 95 Save up to 15% 40-6M A s crewdriver antenna, often used for mobile installations, can make a stealthy antenna planted in a rock garden or among shrubs. . The SWR might be over 2 : 1 on 10m using a 4 : 1 balun at From these two charts, it can be seen that the optimum NVIS frequency falls between the D-Layer absorption frequency of 4. 10-160 Meter. Radiates best as an inverted V, but can also be setup as a simple long wire. 00 Ultralight 40-6M Off Center Multi-Band Portable/Stealth/QRP HF Ham Radio Antenna. A wide range antenna tuner is required for greater frequency coverage on 80 meters. Use a tree Band: SWR: 10 Meters: 1. Furthermore, it’s easy to build, low cost, does not Recent changes. You want the high current portion of the antenna at 1/2 wavelength above ground or multiple of that for low angle. 225 MHz, indicating that the 40-meter amateur band is the optimal band for First, let me make one bold statement: not all "all-band antennas" are truly all-band. The antenna comes with a center support and the The DXE-NVIS-8040S and DXE-NVIS-8040SNM are shortened NVIS wire antenna kit version that features loading coils to make the 80 meter dipole legs the same length as the 40 meter dipole legs, 34 ft.
