i typed a long drawn out post about the i10k then decided not to post it, but to summarise, the i10k is the best built and best performing 5/8 antenna i ever used, not by a huge margin like some would have you believe but there is an edge and the ability to achieve a perfect match over a wide frequency range is something else, the imax is the best fiberglass antenna i ever used but they way too weak for english weather no matter what anybody says, if you dissagree then you simply dont get antenna destroying weather like we do here, the i10k beats the imax where i live and that is a fact not some cb bullshit mythology, i could see a situation where the imax may win out over the 10k like in real hilly areas maybe, imho all that really matters is that we are all happy with what we have up in the air.
