An easy way to 'fly' on eighty meters band. Ideal for limited space. How start: When I was amateur radio I looking for a high efficiency antenna which need limited space on eighty meters band. This happen because my neighbourhoods don't leave me to prop a simple wire. Well I find a way to solve my problem. Searching on antenna book find a half slope for one. This page is a collection of short vertical antennas that I built over the years, for the 80 mtr band. With short I mean between 3 and 10% of λ. That is a lot shorter than a standard 1/4 λ vertical. Anything less than 75% of full-size is actually a real compromise. I am not interested in local QSOs, so I'd like my antenna to have a radiation pattern with a relatively small takeoff angle. Therein the 80-meter band is defined as 3500 kHz to 3600 kHz and the 75-meter band is defined as 3600 kHz to 4000 kHz. A simple way to remember what the FCC calls 80-meters and what the FCC calls 75-meters is that the frequency segment where phone operation is allowed is called 75-meters. The remainder of the band where CW, data, RTTY, etc., are allowed, is called the 80-meter band by.

Why Won't My 80-Meter Dipole Cover the Whole Band? Posted date: February 04, 2021 in: Antenna. Why Won't My 80-Meter Dipole Cover the Whole Band? Antenna. Omni-Directional - Circularly (Mixed) Polarized Antenna for 144 MHz / VHF / 2 Meters. August 18, 2015 No comments. Introduction and Background This is an experimental project that may lead to further development in the future, but even. The natural capacity between the turns will tune the antenna to (about) 4.15 MHz, just above the 80 meter band. One of those Jackson 804 / 805 VHF tuning capacitors with about 25pf will tune the antenna down to 3.45 - 3.90 MHz. The tuning capacitor MUST be one with a couple of millimeters between the plates. The antenna has a very high Q so the voltage across the capacitor will be very high. As I am interested in the low end of the 80 meter band (3550 - 3650 kHz), I will need to get a capacitor with a larger max value than the trimmer I used for this experiment. The second set of plots below show a full HF sweep from 1.5 to 30 MHz. With the antenna outdoors, there are additional dips at multiples of the base resonance frequency. As to be expected, they don't coincide with 50 Ω.

Tutorial on the 80 meters amateur radio band - YouTub

We discovered that, when the 80 meter band was essentially useless for short-haul propagation, the 160 meter band provided good communication. There were tradeoffs to using the 160 meter band: Most of us had to put up compromise antennas that would fit on a city lot -- like the end-fed Marconi . These antennas were not as efficient as full-size dipoles. The only practical way to compensate for. A doublet antenna (dipole), cut for 80 meters, will not work on 40 meters because 7 MHz is an even harmonic multiple of 3.5 MHz. This means that if we try to feed 7 MHz to 3.5 MHz (80 meter) dipole, the 7 MHz current would be at a minimum (null) at the center feed point of the 80-meter dipole The fewer bands, the fewer high impedance regions to avoid. You also want the antenna to be at least 1/4 wavelength long for each band you plan to use. For instance, to work 40m be sure the antenna is at least 10m or 33' long. Use only the white gaps for your antenna lengths, and if you're using different ham bands than in these examples, modify and rerun the program as I did, above, for my K1. EUR 80,00.

A 40 meter loop requires less than 130 linear feet of insulated wire. That is a square of only 33 feet per side. Nearly any suburban residential lot should be able to accommodate that size. Remember the sides need not all be equal, it can be almost any shape that encloses the largest area possible. EXPERIMENT! At first blush, this design may appear to be. I mostly use 80, 40 and 20 meters with 100 watts out, and have found this antenna will auto tune with either radio's built in tuners anywhere from 10 to 80 meters on amateur HF bands with surprising results.

The packages include industry-leading instructions and technical support. Antennas are the most important tool in a successful radio. A typical single band double bazooka in free space would have an SWR max of about 3 to 1 over a 200 kHz bandwidth on 80 meters, with a power loss of about 10%. The crossed double bazooka would have an SWR max of about 2 to 1 over the same bandwidth, at the expense of 30% loss in power. Even with the crossed double bazooka, to get down to a max SWR of 1.5, you need some extra loss on top of. SWR bandwidth on 80 meters is 75 kHz, centered on 3.79 MHz. A good antenna tuner can extend the operating bandwidth on 80 meters well into the CW portion of the band or into the General class phone portion.

The 80-meter azimuth pattern is taken at an elevation angle of 45 degrees. As the elevation pattern shows, most of the radiation is above this angle. Some hams call the relatively low dipole a cloud- burner. Although this is not a DX antenna, there is plenty of useful radiation for all kinds of excellent 80-meter QSOs. On 40 meters, the all-band doublet has a narrower pair of lobes, but the.

When the 80 and 40 are about 4 inches apart, the two elements act like one wide element on 80 meters. This made 80 meters a wide band dipole. When the WARC bands, 30, 17 and 12 meters became available and I had the radio, I tried making one parallel antenna for all bands. With 4 inch spacing, that did not work. I created two parallel dipoles with one being 80 through 20 and the second being 20.

The 80-meter antenna is a 130-foot dipole, fed in the center with 70 feet vertical and 30 feet horizontal 10 feet off the ground and 80 feet off the ground. Think of it as an inverted L fed against an L. The two Ls are balanced with respect to each other and because the currents in the horizontal sections are out of phase, the antenna has a minimum of horizontal radiation. The 80 meter and 160.

The 80 Meter Off Center Fed Antenna (OCF80Q) is also a great multi-band antenna. It is a heavy duty QRP/Low Power antenna that uses #14 wire instead of the usual #16 wire used by our other QRP/Low power models. This antenna also uses a 4 to 1 Guanella Current Balun this is rated at 250 watts, all stainless steel hardware, and covers the following ham bands: 6, 10, 12, 17, 20, 40, and 80 meters. If you just did this your SWR's (Standing Wave Ratio) would be the following in the following band's: Meter SWR 80 4.5* 60 >10** 40 1.4 30 >10** 20 1.3 17 1.4 15 >10** 12 1.2 10 1.6 If you don't want to have to use a tuner you really want to keep SWR below 1.5. If you use a tuner to control SWR lets say taming a high SWR, there is no tuner I am aware of that will bring an antenna's SWR down. 3.500-4.000 MHz (80 and 75 meter) and 7.000-7.300 MHz (40 meter) bands are not available due to ionospheric conditions. It concluded that such an allocation represented the best compromise available to give the amateur service access to new spectrum while assuring the federal government agencies that their use is protected. At the request of the National Telecommunications and Information.

In other words an 80-meter Windom 137 feet long would have one leg 45.667 feet long, and the other leg 91.333 feet long. After spending some time modeling OCF antennas, the closest antenna I could find to a true multi-band dipole with reasonable SWR on most bands had an 80%/20% leg length and 200-ohm feedpoint. This would be 109.6 feet for one leg, and only 27.4 feet for the other leg. The. Band Stacked Element Phasing/ Wavelength Watts (PEP) Connector Type Weight Lbs.

Fortunately, that fact tends to level the playing field for most hams on 80 meters. Any good CW or digital mode urban operator knows that 50 watts into a system to get 10 watts of effective radiated power will still provide satisfactory operation. If you. Just change bands on the radio from 40 to 80 meters and transmit. A shortened Fan Dipole is a dual-band dipole with a full-size dipole also tied to the same center insulator. A good example of this would be a standard 40- and 160-meter dual-band dipole (2B4016) and an 80-meter full-size dipole in an inverted vee configuration with the same common feed point. This package will give you the same.

80 Meters. To cover the other eight HF bands, separate crystal controlled converters convert the signals down (or up) to 80 meters. This makes the receiver dual conversion on every band except 80 Meters. In the old vacuum tube days each homebuilt amplifier stage was designed to work on several bands. This meant that the front panel of a 1970 homebrew receiver usually had a bunch of. Amateur Radio QRP Calling Frequencies QRP is one of a set of quick-to-send symbols beginning with the letter Q, for Quick. O riginally QRP was sent in Morse Code to quickly communicate that a station was using Reduced Power. Over the many years since that time it has come to generally mean very-low-power, rather than reduced power The AM Forum > Band Watch > 80/75 Meters.
