Yes. OCFD's are cut for resonance on the lowest freq. Since our bands (well, most of them) are harmonically related, the OCFD is resonant on those related bands too.
So, all you are doing by making it OCF is to move the feedpoint to a location on the wire that is a standing wave current loop (a high current point as opposed to high voltage point (current node)) for more than one band. Some use a higher Z feedline and some use a transformer to match to coax to accommodate the higher feed Z on the OCFD.

I think I'm going to save up and get the LPA-100. I hope I'm not asking a silly question. Can a multiband OCF dipole be resonant, meaning a SWR of 1.5 to 1 or less, on one or more bands? I know a regular dipole can be, once you take the time to tune it. But don't know anything about OCF dipoles. 73 Rob KC5RET ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This email message is for the sole use of the intended recipient(s) and may contain confidential and privileged information of Cameron and its Operating Divisions.
