DMS INTERNATIONAL INTRODUCED A NEW 90 CM OFFSET ANTENNA AT THE END OF JULY 2007. THIS AUTHOR THOUGHT IT MIGHT BE WORTH USING ON SOME FUTURE PROJECTS, AND DECIDED TO RECREATE AN ANTENNA TEST SETUP SIMILAR TO THAT DONE IN MAY 2006 FOR THE COMPARISON OF COMPETING PRODUCTS. WE CHOSE TO TEST BOTH THE 75 CM AND 90 CM MODELS OF THE HOT DISH ROUND OFFSET ANTENNA, ALONG WITH AN 85-CM ELLIPTICAL ANTENNA MADE BY PATRIOT ANTENNA, AS WELL AS OUR FORMER (NOW OUT OF PRODUCTION) "GOLD STANDARD", THE EXTREMELY WELL-MADE PARACLIPSE 90 CM MILLENNIUM ROUND OFFSET ANTENNA.

READERS MAY WANT TO ACCESS OUR PREVIOUS TEST DATA, LOCATED ON THE GLOBAL COMMUNICATIONS WEBSITE AT www.global-cm.net/antennatests052406.html

RESULTS OF THE NEW TESTING ARE CONSISTENT WITH THE MAY 2006 TESTS, AND YIELDED SOME PLEASANT SURPRISES ON THE PERFORMANCE OF THE NEW HOT DISH 90 ANTENNA. DEPENDING UPON TRANSPONDER AND POLARITY USED, IMPROVEMENTS OF ANYWHERE BETWEEN 0.5 AND 1.0 DB CAN BE EXPECTED OVER THE HOT DISH 75 MODEL.

WE USED THE PATRIOT 85-E ANTENNA BECAUSE ITS SHIPPING CARTON HAS DIMENSIONAL MEASUREMENTS THAT FALL JUST SLIGHTLY UNDER THOSE THAT TRIGGER PUNITIVE INCREASES WITH UNITED PARCEL SERVICE AND OTHER PACKAGE CARRIERS. 90 CM ANTENNAS CAN BE TRICKY TO SHIP AT A FAVORABLE PRICE, WITH BEST SHIPPING COSTS OFTEN FOUND WITH DISCOUNT MOTOR AND AIR FREIGHT SERVICES. POTENTIAL CUSTOMERS, ESPECIALLY IN THOSE REQUIRING RESIDENTIAL DELIVERY TO REMOTE RURAL AREAS, SHOULD BE EXTREMELY CAUTIOUS AND DO SEVERAL COMPARATIVE QUOTATIONS WHEN CONSIDERING 90 CM MODELS. THE PATRIOT 85-E FITS IN A NICHE THAT ALLOWS REASONABLE SHIPPING, WITH A TYPICAL 0.5 TO 0.7 DB IMPROVEMENT IN PERFORMANCE OVER A 75 CM MODEL. THOSE WANTING ANOTHER POTENTIAL 1/4 DB OR MORE SHOULD CONSIDER THE HOT DISH 90, IF SHIPPING COSTS ARE NOT AN ISSUE FOR DELIVERY TO YOUR LOCATION. PLEASE NOTE THAT THE PARACLIPSE 90 IS NO LONGER IN PRODUCTION, BUT WAS USED TO POSITIVELY CONFIRM THAT THE HOT DISH 90 IS NEARLY EQUAL IN PERFORMANCE, AND READILY AVAILABLE AT A VERY REASONABLE COST.
