Buddistick portable vertical antenna by Budd W3FF

Buddistick portable vertical antenna

You're looking for a small size antenna, lightweight, fast assembly and disassembly, easily transportable in a backpack or in your luggage and can cover a wide frequency range. This antenna is really the one you need.
The Buddistick standard package is delivered without coaxial cable and no clamps for attachment on a garden table or other similar support. These 2 items are obviously available on the Buddipole website as well as the tripod mast, small or large model.
Personnally, I opted for the small tripod mast 31.5in high and weighing 1.54 lb that you will easily find in any of your local photography shop.

Below, the Setting table shows last measurement made on Buddistick antenna during saturday 14th. The indicated colors on the table is referring to the color of using Tap connected to the coil (See Pictures 16 and 18), a bit of fantasy that allows antenna changing band faster and easier.

The settings are indicative, they may of course vary depending on the type of soil, environment and length of radial used. These settings are based on those made by default, by our friend Budd W3FF, they allow those who do not have an analyzer, to adjust the antenna with a simple SWRmeter/Wattmeter.

1- Parcel from customs on feb 05th 2009


2- Buddipole and Buddistick antennas package


3- Invoice including shipping cost


4- Antennas parcel from USA


5- Small and nice Buddistick portable bag


Photos 1 to 6
The packaging is first rate, the Buddipole and Buddistick perfectly fit in the same box. The Buddistick Bag is made of solid Cordura-nylon fiber about L13.80in x H8.27in and zip closure makes the bag completely sealed.

The bag of Standard Buddistick contains:

* 1 Coil measuring 4.53in in lenght and 1.77in in diameter
* 2 Alu Black arms with 3/8" screw, length 11.22in each
* 1 telescopic 6 strands whip, total length 66.34in and colapses to 13.19in
* 1 set of 3 Taps clip on the turns of the coil if necessary
* 1 Kite winder with 31.5ft radial made of 1mm2 silver-plated wire ending by a ring
* 1 alu support plate with a PL-259 connector with a 3/8 screw for antenna fixation

The QTH is located at 390 ft above sea level within the Coastal Radio Station of Nouméaradio/FJP, the Buddistick is settled just a few meters from the main building.

The equipment used for the first tests of the Buddistick antenna is a YAESU transceiver FT-857 with 30w output, and powered by an ALINCO model DM-330MVE, 220V-13.8V.

11- Buddistick on tripod mast with SO-239-3/8 connection


Photo 11
The Buddistick is tuned on 7013kHz and mounted on a photo tripod mast about 31.5in high. This system is the one I chose, it allows me to move the antenna precisely at the desired position, it weighs about 1.54lb and it is available in any photo shop at a really abordable price.

A closer view on which you can see in the background, the blue wire radial of 31.50ft length for 40m band, hanging from a tree.

The picture on the right side shows the Buddistick coil, the mini-banana plug is not connected because not necessary on 40m band.

15- Tap 1


Photos 15 to 18
On the left, pictures "Tap1" and "Tap2" show us the fixation of a tiny jumper that is screwed on a turn of the coil. 3 longitudinal recesses arranged by 120° around the coil, make the tap to be moved around the coil on a setting defined by the chosen frequency. Just connect the mini-banana plug onto the tap which is a short-circuit or a shunt at the considered frequency.

Tips for those using an analyzer

Settings for your antenna, the Tap is set on a turn, for example on the 20m band, you get to the first reading 13300 kHz, assuming that the SWR is correct, and you want to work on 14150 khz. Simply move the Tap turn by turn, up and if needed 1/3 turn to the left or right.
When you get a correct SWR close to the desired frequency, you can finely adjust by varying the length of the strands.

To tune on higher frequency = Move turn by turn up and 1/3 turn to the left or right = Ex: 13200 khz => 14200 khz. Reverse procedure to lower the resonant frequency.
To make a fine frequency tuning up = Reduce the length of the whip. Ex: from 14050 khz => 14150 khz. Reverse procedure to lower the resonant frequency.

24- Buddistick antenna is ok for a SOTA DXpedition !


Result of Buddistick antenna Tests

15 February 2009

Having tuned the antenna vertical portable Buddistick, I could begin the first tests, the propagation being open earlier on 40m so it is quite naturally on this band that I started the testing program.

The VKs and ZLs are being too close, the signals coming through very QRO and saturate the reception. It's a fine business! The sharpness of signals received is equivalent to a normal vertical antenna such as R7 Cushcraft or AV-620 of Hy-gain.

First contacted DX station was PA4RI. My report 559 and his RST 599. VKs and ZLs signals were all at 20db over S9, it's not about a fuss, the QTH here is still for something.

18 February 2009

New tests have taken place inside ARANC headquarters, Buddistick antenna placed on the ground between 2 large buildings, at only 9.84ft from/and under the 49.22ft high of telescopic tower belonging to the FK8KAB Radioclub. The using rig was a FT-857D with 30w output power and tuned on 7030 kHz. Claude FK8IF was chosen as qualified operator, he made several beautiful DX QSO's, reporting as follow, received signal: his/RST, transmit signal: our/RST:

* FO/N6JA his/579 - our/579
* KH6...his/579 - our/559
* CE5 .. his/559 - our/549
* SM3..his/599 - our/559

I said that the radial wire was south stretched substantially in the long path to Europe. Although this antenna had been presetted, i still not had the opportunity to test it on the other frequencies, . This will be the subject for another topic.

Setting the Buddistick

Above, the table for adjusting the Buddistick allows approximative presetting of your next coming antenna before you start on the air. Measurements were made with the MFJ-259B analyzer, the settings in the field must take into account the environment, soil type, the length of radial (see table) and WX. I did not tested this antenna under the rain, as the coil is not waterproofed, so transmission will certainly be made in "Silent Key" mode.
