However, in April 2016 Arrow Antennas LLC of Cheyenne, Wyoming acquired the rights to the designs of all Gulf Alpha VHF, UHF, and Satellite antennas as well as the rights to manufacture and sell those products. Parts inquiries should be submitted to Arrow Antennas LLC. http://www.arrowantennas.com/main/mail.html — Note from Pete, a few years ago: Important Notice about phasing cables and connectors on the Gulf Alpha circular polarity antennas. For a long time Gulf Alpha used LMR 400-75 as the cable of choice for the phasing of our satellite CPs. Because this cable is so stiff and the bends required to connect the cables on the 70cm antennas was very tight, the crimps were too stressed and sometimes the cable pulled out of the connector. We used the non crimp solder type for a while. These had their own problems in that they would twist and the braid would become totally disconnected. Again the cable would pull out of the connector. We are now shipping these antennas with LMR 240-75. This cable is smaller than it's larger counterpart and should solve the problem. All antennas including 2 meters will have top quality Type N four hole flange female connectors on the T match blocks. No more SO 239's and PL259's. Cable ends are prepared with Times MicroWave strip tools designed for this cable.

I would like to know how to make a 1/2 wave phasing line for my Gulf Alpha 70cm polarity switch. I've lost the original one while moving.

I understand that using a SWR meter is how it's done but I'm not sure of the details. Is there a better way?

I'd appreciate some help.
