membuat trap rotary dipole 40m

Some tuning was needed, the extra lengths I added during construction had to be trimmed off. Using an antenna analyser a low SWR was seen at 7.10mhz and 20.10mhz, other bands would also be fine with the use of an antenna tuner. During testing, using an ALD ATU, the antenna tuned in to 40m, 20m, 17m, 15m,12M and 10m!

Homebrew 40/80 Trap Dipole Design - November 24, 2007 This Antenna design was one that I used about 4 years ago, it worked exceptionally well on 80m and 40m. The size of the antenna makes a Half wave length on 80 meters, and with the traps a half wave on 40m with a SWR (standing wave ratio) of 1:1-1.5 across both bands.Product Details. 40m rotary dipole (7 MHz).

The fishing poles should be as long as possible. A 40 meter dipole is around 10.10 meters per side. As the fishing poles I had lying around were 8.70 meters this is what I used. Most of the mechanical construction is now ready. Wire length and support. The length of the fishing rods is 8.70 meters and yes, too short.Single Trap (Made by Hari) 7.05 MHz, for homebrew dipole antennas.

Pacific Antenna 20 and 40M Trap Dipole Kit. 2020-03-19 Just replaced 4 band trap inverted vee with this Pacific antenna 40-20 trap inverted vee. The SWR curve above gives an idea of how well it is tuned with very low SWR on both the 40 and 20 meter bands. Almost immediately after turning on the rig I heard VA3JH calling CQ POTA and answered him.8′ 1″ OD fiberglass tubing, boom (MGS) 4. 2. GT 4-050 1/2″ Guy Ties, for tips of spreaders (RFJ) 5. 2.

Trap Construction Trap construction is relatively easy, even for those with few manual skills and tools. Figure 2 is a photograph of a trap; FigureI have been using a Cushcraft 40m rotary dipole (actually the driven element of a 40-2CD) for years. It is mounted 3m above a KT34A tribander in a 90deg fashion (parallel to the boom) and it easily outperforms anything else I have ever tried at that QTH with wire antennas. As mentioned before it is also quite usable on 17, 15 and 12m.Glendale West Rotary Club, Glendale, Arizona. 311 likes · 1 talking about this · 4 were here. 2nd & 4th Wednesdays 6:00pm at DAVE & BUSTERS 9460 W Hanna Ln, Glendale, AZ 85305. That's in the We. Now we’ll need to turn our attention to Al-Rukh, aka General Jasoor. Track his lead in the Investigation tab and the map marker will direct you to his base of operations in northwest Sharqiyah .

Measurements of the dipole are: 9.92m from feedpoint to trap, 7.15 MHz traps 0.2m long, 3m from trap to end, and the capacity loads have a radius of 0.5m at the ends. Both sides have the same dimensions. All charts are based on 8m height - increasing height produces lower angled nodes of high gain.K6IF/W6BDN 40 Meter Rotatable Dipole . We designed and built this antenna to mount just below our tri-bander at about 70' on a crank-up tower. It is an excellent all-around 40 meter antenna for those who don't have room for (or can't afford) a yagi, but want more than an inverted V. N6BT has done repeated tests that show that a flat-top dipole mounted at the same height as the apex of an 1. Angel Veterinary Services - At Home Pet Euthanasia.

What's a trapped dipole? A trapped dipole is a dipole with blocking filters fitted at the operating wavelengths. For example, a 40 and 20 metre trapped dipole would have traps installed at the 20 metre points which would prevent the 14Mhz band, effectively shortening the antenna.THE TRAPS The traps are made from 85-90mm long pieces of 49mm OD PVC plumbing pipe (DN-40), with holes spaced 60mm apart for the trap termination screws. The 80 metre trap is 26 turns of 1.25mm enamelled copper wire (about 4.15 metres of PEI wire required) coiled to 40mm in length (i.e. closewound) giving an inductance of about 25.7uH.Rotatable, motor-tuned dual-band dipole with coverage of the COMPLETE 80m band + 60m, incl. controller with touch screen.
