Information about 1090SJ mk 2 Antenna
The manufacture of this antenna has recently been sold. I have received a sample of a new 1090MHz antenna and I am sorry to say it is not of the quality that I expected, so I will no longer be selling a 1090MHz antenna.

I will be leaving the information about suitable Coaxial Cables for 1090MHz, and the Accessories, etc. which may be still of interest.
COAXIAL CABLE FOR 1090MHz NOTE: I do NOT sell Coaxial Cable or Connectors
asp hit counter
There are many different coaxial cables to choose from for 1090MHz, with large price differences both in the cable and the connectors. The fitting assembly for some connectors is by no means easy. Due to the stiffness of some cables the bending radius has to be seriously taken into consideration. Below is a list of various coaxial cables that may be used. I have included the loss at 5, 10 and 15mtrs. Please note this is approximate and does not include the 2 connectors. I suggest you contact Henry Westlake, a specialist in coaxial cables, and he will make up the length you require with the appropriate connectors. Contact him via: +44(0) 1409 253758 or whwestlake@hotmail.com
For a good all round price, loss, ease of use, then Westflex W103 is a good choice.
NOTE: Please find some prices from H. Westlake for a few made up lengths of the popular Westflex 103, Low Loss Coaxial Cable. High Quality "N" Plugs and "BNC" Plugs.-
