Hi.... Any good quality two port splitter can be used as a same-band combiner. There is no advantage to overspending for a "monster" name brand or for any frequency coverage above 700 MHz although GHz is probably going to be the common specified range. A $5 Ideal splitter from Home Depot will do the same job and you can pick one up locally without any shipping charges. If you're already buying something else from MCM, the one you cited is fine as an add-on to a larger order. I wouldn't buy it specifically by itself just because of the shipping cost.
