I am combining a pair of eight 2SC2879 KW amps for 160-10M
and need to acquire a Splitter & a Combiner.

RF Parts  www.rfparts.com/combiner.html  appears to have the
splitter and combiner I need.

I will be driving them with a TenTec Jupiter so for a
Splitter I'll use the COM-2 Input/Output  .5 x .5 300W $3.75

The dual 1KW amps will merge power via a Combiner -- COM-6
Output .5 x 1.2 2800W  $6.65

Is the COM-6 adequate or should I use a larger Combiner?
(I am less concerned about cheap and more about appropriate.)

COM-10     Output*     .5 X 2.4     5000W     $19.95
COM-20     Output*     1.0 x 2.4    10,000W   $36.95
*includes 100W termination resistor.

Also, what is the purpose of the terminating resistor for these
two devices that is not included with the smaller ones?

Any additional considerations in the implementation of the
splitter and combiner, please?
