I’ll try get a photo this weekend. I’m hoping to use it for 10/11 metres.

Yes I have removed the link start as its seems to be gone. Thats the trouble with the web, no stayers!

Anyway search on swiss quad for best info.

If you look from the top it has the centre boom which is VERTICLE in the centre and four radiating elements in a flatened cross for a metre then they bend flat like below. one above the other separated by about a quater wave 9′ and the ends Verticaly attached by copper wire.

Damn that was harder than I thought to do.

The smaller square obviously is the driven element and the slightly larger back square is the reflector.

SWISS Quad – Greatest allround CB antenna of all time??
by AX05 » Fri Dec 28, 2007 8:29 am

I have used a Swiss Quad antenna to gain most of my countries on 11 metres. I had to find a high gain directional antenna that fitted within the legal guidelines of the Australian Communications department in the late 70’s – i.e. NO parasitic gain elements allowed on 27mhz CB.

The only antenna that seemed to fit the guidelines was the TET Swiss Quad or HB9CV Ham antenna.

It certainly performed better than anyone else seemed to do at that time on CB in Melbourne Australia from what I could ascertain.

If I could hear them – I could work them with only 15 W PEP from a CPI CP2000 Base station.

Some more official objective views below…

 
Creation : August 2001
Subject : SWISS QUAD Antenna, issue 10
Alain Miqueu, F6ITV

Was HERE BUT GONE: pagesperso-orange.fr/f6itv/p2045001.htm

Which monoband directional antenna can provide a good gain, a good F/B ratio, being not to large and mechanically within hamradio skill? As it is used to say, it’s a process that consists in searching the best compromise.

q This excludes high-gain and long-boom Yagi that are very large and heavy.
q A 3-element Yagi could be suitable regarding performances but to me it’s still too large.
q A 2-element cubical quad could be suitable regarding performances and sizes, but mechanically it’s rather complicated and fragile.
q The well-known Mr Baumgartner, HB9CV, has implemented a 2-element tubing antenna that has the both elements fed with such a phasing that it gives it better performances than a 2-element Yagi.
In Europe the HB9CV antenna is widely used in VHF and UHF portable experimentation but also in HF. It has a lot in common with the ZL Special, see W4RNL : http://www.cebik.com/hb.html
q HB9CV also transposed his feeding system to the 2-element cubical quad, this allowed him grounding the both loops, a genius idea for a unique model, he called it SWISS QUAD. It took me fancy at
the time I saw it, even if it seems mechanically more complicated than a 2-element Yagi, in my opinion its construction is easier than a classic quad owing to its all-grounded feature.

To day I have built two Swiss Quad, one for 28 and another one for 50 MHz. So I take web opportunity in bringing this benefit to who is interested in building this antenna because it’s really fancy and it will give you excellent DX performances together with the satisfaction of its construction.

Notes

q I remember that in 1990, a JA OM has informed me that experiments have been carried out on 10m
to add parasitic tubing elements to the Swiss Quad (Swiss Quagui ?) and also to make stacked
arrays with the resulting antennas.
q Also I remember that in the 90’s the Japanese Company TET has commercialised this kind of antenna
for the 144MHz band.

CLAIMED PERFORMANCES

q Gain against a dipole at short distance 6 to 7.9 dB
q Gain against a dipole at long distance 12 to 14 dB
q F/B at 15 km 15 dB
q F/B at 1000 km 10 to 12 dB
q F/B at 3000 km 18 to 24 dB

2010 Oceania Contest -ON NOW! 2/1/2010
by Bellhopper » Sat Jan 02, 2010 5:21 am

2010 Oceania Contest
The world’s best on-line DX magazine, 11m DX Activities Oz, is proud to announce the dates of its 2010 Oceania Contest. Undoubtedly the most exciting and best supported contest on the eleven meter band, the 2010 Oceania Contest will commence on January 1 with the aim being to make as many contacts with Oceania DXCC as possible over 2 long weekends.

As always, a number of high profile communications retail outlets have volunteered to sponsor the event in the form of some outstanding prizes for placegetters. Dave and Mike from Yeti Communications, for example, will continue their generous support of the OC Contest by way of donating one of its brand new super rigs — especially designed for the professional eleven meter band DXer — as a prize. Jos Hanhn from Syncro is back on board in 2010 again too, throwing bucket loads of prizes at the event to show HIS company’s support for OC DXers! There’s also a major prize offered by Dave Cox and the crew at Radio Warehouse Australia up for grabs to tickle the fancy of serious 11m contesters!

The rules for January 2010 remain the same as this year’s event and are designed to provide fair and equal access to all. Please read them carefully — particularly how scoring works for you, depending on YOUR geographical location (OC or NON-OC). If you have any questions, please add a comment to this story or email me direct.

On behalf of the Admin Team, good luck!

[Please note that 11m DX Activities Oz and/or Contest Organisers, Sponsors or Supporters accept no responsibility for operations outside of your country’s legal frequency allocation. In fact, adherence to your country’s frequency limitations is encouraged].

SCORING

For Oceania Transmitting Stations:

* Each contact with a station in your own DXCC is worth 1 point
* Each contact with an OC transmitting station outside your DXCC is worth 1 point
* Each contact made with a non-OC transmitting station [Example: A station in EU or the Americas] is worth 3 points
* Only one contact per station on each weekend will count in final points score
[NOTE: It is possible to work the same station on 2 occasions during the Contest providing it is on different weekends]
* At the conclusion of the contest, each DXCC worked adds 3 points onto your TOTAL points score [Example: 43 SE 144 Peter works 43, 9, 2, 41, 172 and 224 = 6 DXCC = 18 points]
* Points are then multiplied by the number of OC DXCC worked (Not OC stations worked) to give a FINAL points score.

For Outside Oceania Transmitting Stations:

* Each contact with an OC transmitting station is worth 3 points and counts as 1 multiplier [IMPORTANT NOTE: No more than 2 multipliers per OC DXCC will count] [Example: if you work 2 x 43 division stations, total = 6 points + 2 multipliers) [If you work 10 x 43 division stations, total = 30 points + 2 multipliers]
* Only one contact per station on each weekend will count in final points score [NOTE: It is possible to work the same station on 2 occasions during the Contest providing it is on different weekends]
* Each contact made with a non-OC transmitting station is worth 1 point
* Contacts are possible within your own DXCC and are worth 1 point
* At the conclusion of the contest, each DXCC worked = 3 points onto TOTAL points score [Example: 14 FR 003 works 14, 161, 26, 41, 43, 47, 13 and 2 = 8 DXCC = 24 points]
* Points are then multiplied by the number of OC stations worked (Not OC DXCC) (Limit of 2 multipliers per OC DXCC) to give a FINAL points score.

[IMPORTANT: To be eligible for final placings, including prizes, in the Single Operator Category, an outside of OC transmitting station MUST have worked at least 1 x OC transmitting station].
