160m Vertical Antenna Design

Since each leg was originally 40 feet long the loading coils were placed at the 28-foot position. I already had 160m capability but wanted to add to it and so the story begins.

Cq Low Band Dx M0sdv

Many amateurs shy away from 160 metres due to the bands imagined large antenna requirements.

160m vertical antenna design. Parallelkreis-Koppleer fuer 160mpdf PDF-Dokument 1666 KB. The 160 meter loaded vertical antenna is constructed using an inexpensive Telescopic Fiberglass Fishing Pole 10m in length. For a variety of reasons we may be restricted.

A reproducible short vertical antenna for 160m using a resonant top hat using readily available aluminium stock and hardware featuring tilt over erection a base insulator permitting easy feedpoint matching and total height no exceeding 7 meters. Ive made a number of versions of this antenna which have now diverged into two variants. Parallel Antenna Coupler for 160m Parallelkreis-Koppleer fuer 160m by Alfred Kluess DF2BC as published in the May 2011 issue of the DARCs CQDL magazine on page 332 and 333.

It is a 25 ft. However especially if one operates portable one can still do quite well with simple antennas that are a fraction of a wavelength tall. If you want the design details just Search on it or go to the ARRL Antenna Book or any of the many great reference Sites and books out there.

A capacitance hat is on top and the antenna is fed with a 50. Shoddytenna 160m portable antenna. Having had some success with short 8ft-long mobile aerials for ground-wave contacts on 160m I was intrigued by the idea of making something a little larger for portable use.

This antenna is suitable for amatuer construction in a suburban situation where a larger tower is impractical. Good Vertical Antennas A straight quarter-wave Best λ4 125 ft at 1830 kHz with THHN Inverted L Good Go straight up as high as you can with a wire then bend the remaining wire to run horizontal to resonate it Tee vertical A bit better than L Like an inverted L but the top is extended in opposite directions. 160M Inverted L.

This 160 meter antenna is a single band antenna. An ideal combination for portable use. If you want to try to use this antenna on other HF bands anyway you will need to use a wide range antenna tuner to handle the unpredictably high VSWR values.

I got to meet John K6MM at an NCDXC meeting and got word about an antenna he designed which was published at one time in QRZ. You can find Johns plans here on his website. In reflection Im very glad to have added the 160m operation as that is a fascinating band.

Shorter verticals are possible but you have to be creative. 160 and 80 m antennas since I had no antennas for these bands the antennas had to be hidden because of covenant restrictions open wire feeders would be too visible to be allowed. While its desirable for a vertical to be a full 1 4-wavelength high on 160 meters thats 130 feet and many times thats not possible.

Resources listed under antenna category belongs to Antennas main collection and get reviewed and rated by amateur radio operators. This antenna is designed for stations having a difficult time putting a decent signal on 160M from small or CCRd lots. If there is enough interest I could do a full post on building and using an Inverted-L as an NVIS antenna for 80160 meters.

160 Meter Verticals Few amateurs have room for full sized vertical antennas on 160 meters. Tuning a 160M full sized vertical with strong AM broadcast RF present on the antenna. Using EZNEC Woody calculated parameters for a base-loaded coil that would not only electrically extend the antenna but also eliminate.

It said 45 ft not 43 ft. 13 26-AUG-2013 10 Description and Theory 11 Antenna Description The Spiderbeam Model 160-18-4WTH is a base-fed electrical quarter wavelength vertical antenna built on a Spiderbeam 18 meter high telescoping fiberglass pole. K6MM 160m Antenna.

It uses 4 top-hat. The antenna was tuned for 1840 kHz to maximize FT8 digital mode operation. Its now on its second version v2 with a conversion from a trap-based to relay-based band selection and.

A loaded base-fed vertical by Ross Wilkinson G6GVI. 160m80m Transmit Vertical by AC0C. The last series of compact 160 meter antennas were not that satisfactory.

160 meters band antenna category is a curation of 150 web resources on 160 Meter Dipole 160m Vertical Hex-Shaped 160 Meter Receiving Loop. With some creative modeling we can. 160m Top Band End Fed Antenna -G3YEU Coil Details- 5 127mm diameter using 16 SWG bare copper wire.

Luckily there is an easy relatively compact and better performance 160 meter antenna design available created by Rudy Severns N6LF Another Way to Look at Vertical Antennas described in practical notes on John Taits Antennae for the Low Bands page. Spiderbeam 160m Vertical Model 160-18-4WTH 5 160-18-4WTH Manual Ver. Here is by build and experience with it as well as final results.

Wound at 35 TPI 35 turn per 25mm Number of turns depends on the length of the antenna. Vertical antenna made from three 10 ft. Two articles or paragraphs I read somewhere stated that most of the serious 160M DXers in Europe use a 45 ft vertical aluminum mast for their work.

The vertical antenna I have has less than 8 radials that is just the way it is going to be. Assuming the antenna wire is 38 wavelength at the bottom of 160M and both coil and capacitor are variable or switchable then the antenna can serve well as an NVIS antenna across all of 160M and 80M. Described here is a lightweight vertical based around a squid pole that can be.

The lightweight construction make it easy to handle and self supporting offering minimal wind resistance. I wont bother posting a graphic of this antenna they are everywhere. There are a lot of 160 designs out there on the internet with quite a few adding coils etc to match shorten verticals or top loading with various configurations.

Jay Terleski WX0B I often get asked about how to match a ¼ WL vertical to a 50 ohm transmission line and what to do about lightning protection and even how to make RF measurements in the presence of strong AM broadcast RF on the antenna. Having taken down my other antennas But Im reading a lot of material to get back into DX especially on 160M and 80M. Because the dipole and therefore the vertical – would be limited to 25 height a small fraction of a 160 meter wavelength we knew getting it to tune up on frequencies as low as 20 MHz was problematic.

The 160-meter loading coils Hy Power LC1682 are placed at the 70 point following the design by Hy Power for their 82-foot horizontal 160-meter antenna. PVC sections bolted together and 12 wavelength of antenna wire helically wound around the PVC sections. The 160 meter band is not harmonically related to higher HF bands except perhaps for the 60 meter band.

My feeling is that the coil losses and tricky matching problems with top loaded wire antennas make the inverted L the way to go for simplicity of construction and. This antenna started out as an 80m vertical with160m capability added as a secondary consideration. 160m80m Broadband Antenna by K5GP A presentation to CTDXCC September 22 2008 The 160m80m broadband antenna design objectives were to have.

I used 35 TPI to make tapping easier and to keep the losses down 11.
