More proof that these guys don't understand a damn thing except money in tbeir pockets from unsuspecting customers. Why use 16 pieces of crap when perfectly good real RF devices are on the market that put out over a kilowatt each. A pair would do 2 Kw all day long but they would cost a little bit more than16 of the others. Then again they are almost bullet proof when it comes to high SWR. You get what you pay for.
