Reviews Summary for Gulf Alpha 11 Element Dual Polarity Yagi
Gulf Alpha 11 Element Dual Polarity Yagi Reviews: 1 Average rating: 5.0/5 MSRP: $329.00
Description: 11 element vertical and 11 element horizontal wide spaced computer optimized yagi. Has machined aluminum connection box as the core of the antenna feed system. Uses a driven element with a larger diameter to improve bandwidth. Uses a heavy duty T match. All elements are solid rods. Additional features of this great antenna include a double boom to mast plate which uses 4 V clamps and these clamps are spread over a greater distance. 4 clamps around the mast will result in greater holding power against the twisting forces preventing the antenna from turning and becoming out of sync with the rotor. Innovative element mounting system makes assembly a pleasure and long term reliability assured.
Product is in production.

Outstanding  Time owned: more than 12 months
The Gulf Alpha 11 element vertical and 11 element horizontal beam is an outstanding performer, providing great flexibility by being usable on both FM and SSB. I like to operate both FM and SSB on 2 meters but as you may know FM is generally done with vertical polarization, while SSB is done with horizontal polarization. This antenna provides the ability to use either using separate coax connections for each.

The 11 element K1FO style design on an 18 foot boom provides a respectable amount of gain. The pattern is clean on both polarizations and front to back appears excellent. The SWR is flat across the band horizontally and is only slightly higher vertically.

Previously I had used a pair of M2 2M12 antennas, one mounted for vertical polarization and the other for horizontal polarization. They too are based on a K1FO design with 12 elements on a 19.5 foot boom. I did like them quite a bit and their performance was very good. I needed more space on the tower to mount other antennas and so I switched to the Gulf Alpha. Despite the slightly larger size of the 2M12s and the extra element, It actually seems as though the Gulf Alpha performs at least as well if not better (it could be my imagination). In any case, the slightly more compact Gulf Alpha is at least on par with the 2M12s.

Where the Gulf Alpha is truly different is in its physical design. It is built like a tank. The boom is bigger and thicker. The elements are more heavy duty and the element mounting system is far superior. The mast mounting clamps make the others look like toys. There is no doubt that the Gulf Alpha could withstand much stronger winds than just about any VHF yagi that I have seen from other manufacturers.

So what is the catch? The biggest issue that you will have is getting your hands on one of these antennas. Pete from Gulf Alpha builds these antennas individually by himself. I had a long wait until I received mine. It is clear that he takes the greatest of care in making sure that the antenna is just right. The only other issue is that his assembly instructions assume that you are familiar with yagi design, and so are not for newcomers. Someone without that sort of knowledge may ended up placing a call or two to Pete so that they build it properly. I had no trouble myself.

I am very pleased with this antenna. It has a more streamlined look vs. two separate vertical and horizontal antennas and is more pleasing to the neighbors. It also has created some more room up on the tower for other antennas. If you are into both 2 meter FM and SSB and want an antenna with excellent gain and performance, the Gulf Alpha 11 element Dual Polarity antenna may just be what you are looking for.
