I'm in So. California (So. Orange County) and UPS just delivered two DAT-75 antennas from CPC in the U.K. The box looks like it's the Televes factory box. One box contained both DAT-75s and it is indeed enormous - 6' x 2' x 1'. CPC confirmed that the shipping cost was indeed the same for 1 or 2. The reason is simple - carton size doesn't change and the gross weight (12.0 kg) is mostly box and padding!! Interesting that the freight cost is the same for east or west coast. Or, at least CPC charges a flat rate for US shipments. (50 GBP)
The total cost for 2 antennas and shipping was $196. Thus, the delivered cost per DAT-75 was $98. I don't believe it's possible ship one from Milwaukee to the West Coast and beat that price, per antenna. Even repackaged, the shipping box would be UPS "oversize".
I was the first stop for UPS this morning. The driver said he couldn't get past the carton blocking the walkway in the back of the truck!
EDIT - Upon assembling the antenna, I conclude that the constuction is more robust than other antennas I've seen. The beams/elements appear to be clear-anodized aluminum. No instructions, but a little experimentation is all that's needed to put it together. Later, I recalled seeing an assembly instruction sheet at the Televes web site. It's this PDF...
