Big Signal - 4BS-11 4 Element 27 MHz Cubical Quad

BIG SIGNAL 4 BS 11 Meter Cubical Quad Antenna



At BIG SIGNAL we have the latest generation in the design and development of Cubical Quad antennas for the 27 MHz / 11 m band.

Why choose the BIG SIGNAL 4BS-11 antenna versus a traditional Yagi?

· Full wavelength antenna in 11 meters, reaching maximum performance and efficiency.
· More gain in less boom length than a traditional Yagi of the same size.
· Very low noise: Being a closed antenna, it will allow you to attenuate the QRN and urban noise improving the reception of weak signals in the band.
· Very low radiation angle even when installed at a low height. This allows us to jump less to the DX, which results in a stronger signal to the other side. For this reason it is known that cubical quad antennas are the first to open and the last to close the propagation...
· High selectivity. Excellent suppression of side and rear lobes, further reducing unwanted noise in reject directions.
· Heavy-Duty construction with for extreme durability.

Being in the TOP of the most powerful stations in the 27 MHz band means being the owner of our BIG SIGNAL 4BS-11 antenna. Discover the magic of Cubical Quad antennas and live a new experience in the DX in 27 MHz like never before...

BIG SIGNAL - The ultimate performance.

Spid Rak

Model: SPID RAK



Spid's heavy duty AZ-rotor. This rotator is a step up from the mainstream rotators and provides excellent support for direct round mast mounting. Can be incorporated with an Elevation rotator to provide full EL/AZ capability.

Spid Rak

If you need the best rotator for the biggest arrays, the RAK is for you!

Technical specification:

Angle of turn: 360 + / -180 °
Time of tour: 90 sec.
Supply: 12V-18V DC
Weight: 8 kg
Input signal: pulses (0.66 ° or 1.00 ° per pulse)
Vertical pressure: 120 kg
Maximum net torque: 180 Nm

Rotor and Control Box works well with such programs as ham radio deluxe.



The RAK compared with its smaller brother the RAU



Please note, we supply the USB version as standard, not the RS232 version. The USB version is normally at extra cost!

11 Meter Prefix

Each country has an assigned prefix.

For countries that have licensing restrictions (license required to operate a CB radio), the assigned "call sign" will have one of the following a prefixes listed below.

For those countries that are not restricted to licensing, it is common practice (courtesy) to start your "own" "call sign" with your country's prefix.
As an example; if you transmit from Scotland and you have a made-up call sign of YZ (Yankee Zulu) and are fond of DXing, your call sign would be 108YZ Followed with given unit number.

So when you listen to other DX calls you can now discern where they are from by the prefix in their call sign.

Specification

This antenna is made HD as standard with 22mm diameter which taper to 13mm tips. The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which will support 2 inch (50mm) masts. For other diameters, please ask! Boom is 45mm square tapering to 40mm.

OTHER TAPER SCHEDULES ARE AVAILABLE FOR THIS ANTENNA, CALL OR EMAIL FOR DETAILS

Our antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be, ensuring they work as well as our software model predicts.

Note: Much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the make up of our antennas have least effect on performance and pattern degradation.
