These wreaked havoc with antennas I placed near them in the past. Orb Thompson. I immediately was inspired to homebrew the design but for vertical use. Very similar to the G5RV where it will use a significant portion of the window line feeding the dipole as the radiator itself rather than the dipole legs. Not only can this type of dipole be used horizontally, you can also use it in an inverted-v or sloper formation – perhaps as an 80m/160m version? The overall length of my 40m version is 12m / 40ft for the 40m band. The Tak-Tenna just sounds a bit too good to be true - it is basically a half wave dipole reading most reviews it appears that the longer the feed line then better it works! however if you wish to try one then they are easy to build see. Compare that to the typical 40-meter dipole or Inverted-V configuration ! Thus it has the advantage of space-saving and unobtrusive setup when compared to other design of HF-antenna.

Background top TAK markets and sells a 40-meter antenna that is a unique arrangement of a simple dipole. Only at eHam. Agreed, but the spiral caphat/inductor on the Tak-tenna is a bit different, the coil section which you tap with alligator clips for each band of operation is effectively inboard of the cap hat portion that pulls current and allows the inductor to provide loading. In essence, it's a two element five band antenna. And living in an HOA and/or CC&R defined community typically weighs toward a compromise situation. The wavelength is what you need to build effective antennas. GENERAL: Each TAK-tenna is designed for resonating - ONLY ONCE - on your choice of frequency on the primary band.

Windom antenna is an off center fed dipole,The WA-4 is a typical Windom type antenna that can operate at 40m,20m,10m,6m band making it an ideal portable antenna. Having my Amateur Radio License since December 2009, it was a real challenge to come up to speed fast enough so that I was able to create a "radio in a box". All four have the same gain and the same radiation field: a torroid (doughnut shape). First: we recommend that TAK-tenna be resonated for maximum performance which provides maximum satisfaction. To put that in perspective, a full-size half wave dipole for 40m is 66 feet long. According to various reviews, it appears to work well. Depending on which bands you want to operate, there is a better design which involves shortening the antenna and lengthening the section of ladder line. Apparently, it is dipole made of two flat spiral coils. fritzel mfb 23. Reproducibility of VT was excellent. Using this time reference, it of course follows that the vertical sync pulse for the next field must begin 1/60 second later (since there are 60 fields per second) ; this is shown by part (B) of the figure so. I've got a friend in Texas who's quite a welder and he'll weld me together 4, 40 ft tilt over poles for the support. the 40 meter position, as shown in Figure 1. (please see FAQ #3 ). Only at eHam. Dipole antennas are good and ideal dipoles are one-half the wavelength. Notice the poor tower sitting on the ground, and the steppir on the left of the shack on sawhorses. The SWR was about just a shade under 2:1 and we could have got it much lower if we had carried on checking. (made from fibre glass), omnidirectional and gives full size dipole performance on all 5 HF. The magnetic loop is small, reasonably efficient even close to the ground, has a low take off angle and it has a deep null on each side which lets you null out interference. Later, I will update this page with more details of my build, mods, dimensions, and most importantly, the antennas performance. Instead of leaving the arms straight, he wrapped them around each other, forming a spiral. I have been on "limited work" recently due to an injury and have been surfing all sorts of Ham Radio related web-sites. I immediately was inspired to homebrew the design but for vertical use. Tista end fed bi verjetno delovala bolje, kot zvita G5RV antena. ALE Auto Tuner V Dipole (c)2007 HFLINK 40 Meter TAK-tenna or TAK Antenna Project Overview: So I've been reading about this Small Space antenna (Small Spa. 8 MHz would be 80 meters long (or just over 262 feet if you refuse to use metric). revelando a tak-tenna (brow dipolo)para 40 e 80 metros terça-feira, 20 outubro 2009 8:50 pm Ψ um conceito criado por alan r. Already have the materials to build a 40 meter spiral loop. And living in an HOA and/or CC&R defined community typically weighs toward a compromise situation. Hi Jeff, VE1BLL and the Group, The spiral coil is 1 foot square and has 24 turns of 1/8" aluminum tubing. 3 out of 5 by 142. I've got a friend in Texas who's quite a welder and he'll weld me together 4, 40 ft tilt over poles for the support. Very thin wire can be virtually invisible and can be used in many configurations. mfj 1775 dipole. fritzel mfb 23. Windom antenna is an off center fed dipole,The WA-4 is a typical Windom type antenna that can operate at 40m,20m,10m,6m band making it an ideal portable antenna. All it takes is an RF choke to reduce those coils into into useless loops of wire.
