Some amateurs obtain good performance with end-fed ½-λ wire antennas. " Although more expensive than Unadilla traps ($76/pair versus $52/pair), the mechanical design seemed more robust so a pair was ordered. ) When resonance or low SWR dips are far from the correct frequency, use this coarse trap tuning adjustment procedure. We've tried 60m on a randomwire and EFHW--it worked marginally well. This filter needs to be readjusted for optimum performance on the 60 meter channels for use in some European countries. Oh…you can use the 40-meter dipole on 15-meters without modification. The 60 meter band is an equal opportunity band. The half-wave center-fed dipole is one of the most popular antennas in use today.

As you can see, very reasonable results for a multiband antenna like this. That’s fine!. A4S is the true, high performance tribander. HF Mobile Antennas. losses on 160- and 80-meters, and will preserve the compromise SWR and relatively low SWR-related losses of the original antenna from 60-10 meters. Posted on Because the MTR doesn't have an ATU or a SWR meter and I don't want to carry anyone of those, I decided to make an antenna. Figure 2 is a photograph of a trap; Figure.

VERTICAL ANTENNAS K4TR 160 METER VERTICAL "T" ANTENNA (MADE TO ORDER) This Antenna Is Taken From A Time Proven Design. If the FCC changes or expands the frequency allocation of this band in the future, a new diagram will be made to reflect those changes. restrictions, and thats the gentlemans band, 160 meters. WiMo is a supplier and manufacturer for radio products suitable for the radio amateur as well as for professional users. The unique design characteristics of this 10-160 Meter HF JPole antenna enables it to approach resonance on the major HF bands (10/12/15/17/20/40/80 Meters), all of which presents an SWR that is low enough for external tuners to achieve a near perfect match, including 160 meters. Industry Canada has announced that a number of specific frequencies within the 60 meter high frequency band have been approved for amateur radio use as RAC advocated. So a big welcome to our friends to the north to 60 meters, and I hope this means a greater use of this nice little quiet band. Again, don’t forget you’re missing 47 pF, so increase the value of C11 (e. Figure 7: The components of my antenna (PVC mast included, fishing poles partially collapsed) I used 2 meters of PVC tube of 4 cm diameter as a temporary mast, stuck into a heavy umbrella stand (see Fig. This tends to be a resonable compromise between trap loss and ease of antenna adjustment. Check the 60m country listings. 160 Meter Inverted-L Bazooka Antenna- A DOUBLE BAZOOKA antenna is an extremely broad-banded Half Wave Antenna that can operate efficiently across an entire Ham band with little change to the SWR. 99 Galaxy DX-939 40 Channel AM Mobile CB Radio Backlit Display Talkback Roger Beep. The coax connector is at one end of the dipole, where it is most needed. 10-160 METER 60' END-FED ANTENNA The Alpha J-Pole Sr Antenna is only 60 feet in length. As supplied, the vertical antenna is designed to operate on 60 meters. It's a rugged homebrew multi-band trap vertical antenna that works the and 20 meter amateur radio bands" Dipole and Inverted V Antenna Basics "This antenna project came out very nice. A trap design guide is provided below to aid multiband dipole construction. Directional Antennas •Yagi-Uda antennas feature a driven element with a passive reflector and director(s) •Monoband Yagis have the best performance •Multi-band Yagis utilize traps and additional elements K4KAY Yagi antennas. Not a monobander but much better gain than a dipole and a front-to-back ratio that you don't get with a dipole. this web site. 60 meters in Poland soon. Homebrew 40/80 Trap Dipole Design This Antenna design was one that I used about 4 years ago, it worked exceptionally well on 80m and 40m. The DX Engineering DXE-60VE-1P is a fast taper 43 feet high vertical antenna system. This Antenna Tuning Unit also incorporates a 50-ohm QRP dummy load, power meter (1 or 10 Watts full scale), and SWR meter! I have used this ATU for a variety of longwire antennas, including outdoor antennas of various lengths and much shorter indoor (attic) antennas. The original was for 160 meters and I cannot say a bad word about the antenna. 8:1, followed by the 40 m wires then the 80 m wires. Hustler Mobile Antennas and Mounts. 75 uhy coil. Learning how to tune an antenna entails lengthening or shortening the antenna so that, for the radio's specific frequency, it is working as efficiently as possible. As a first test I ran my 0. 85mm GPS speedometers 8 Colors Backlight 0-200MPH 300kmh LCD speed odometers US. TRI-BAND ANTENNA ELEMENT TRAP EXAMPLE: EXAMPLE: When a Tri-band 10, 15 and 20 meter beam is excited with 21 MHZ energy only the length of element to the 21 MHZ trap is used. For n working frequencies of an antenna, you need n-1 traps in each part of the antenna. (Tribander, WARC, 2 M, and Accessories) 23. Also for: 5-btv, 6-btv. Back in 2011 when I built the W3DZZ trap antenna for 40 and 30 meters Len Paget GM0ONX who originally came up this particular way the W3DZZ is designed also came up with an inverted L antenna based on another W3DZZ design, I described it earlier in my blog (see the "my Blog" link below). •Need lots of room, keep them away from metal objects like heaters and ducts •Wire antennas can be run near the peak of the roof inside the attic, bent in odd shapes to match the space available. This is especially true on 80 meters. 60 - Lazy Quad Antenna for 10m. 5 MHz (60 Meters to 80 Meters). But we could not find 60m traps anywhere. W3JlP 0th the coil and capacitor of a parallel-resonant antenna trap can be made from the same length of coaxial cable. Single, double-trap, wobble-trap, backup and handicap matches are heldon Saturday and Sunday mornings. Overview: I thought I would share a few of my notes on tuning up a 6BTV antenna, and constructing a radial field. 1SM15-2 15 Meter antenna w/floor or pole mount.
