Hello
In that web site it wrote 144/432MHz of cuting frequencies of that filter.
But VHF stop at 216MHz, so I was presuming that this circuit are cuting the VHF to low or that the text are not clear about the cuting frequencies of this diplexer (combiner) ?
I live in Canada, in mountain, far from any cities, so there is none of combiner sold here arround, and the mail ordering stores for those are only in US and cost more shipping than the cost of the combiner.
