What will it do to the SWR, i.e.: the radiated wattage ? It's hard to suggest quantitative effects without testing a specific poor construction practice. That knot will create a series of high SWR points. So will pulling coax hard if it gets stuck during installation (stretching will change the internal size ratios), hanging it sideways through a hole in the mast extrusion below the head, bad connectors, or pinching from things that shouldn't be resting on it, or overly tight clamps. A small amount of these problems may cause less loss than choosing a high loss cable type (common on boats), a junky non-mil solderless connector (as opposed to mil-crimp type installed with proper tooling) corroding internally, or an unsupported cable run cutting through or pulling out and falling into the mast. JP> I once saw an antenna that the owner had bent JP> into two 90 degree kinks, so it would clear to the JP> side and not stop the windex indicator. Are these two JP> bends doing anything to the radiated signal too ? Yes. It's also like waving a flag saying "clueless jerk to be found nearby", sort of like when kids place car stereo speakers loose on the rear deck of their cars (so that low frequencies cancel between front and rear of diaphragms). Elements of such whip antennas are cut to submultiple resonant lengths, and may have additional components in the base to match electrical impedance to that of coax. Those bends change the effective length and therefore impedance of the antenna, directionalize it to some degree, and cause a space-phasing relationship of current in the whip which may cause efficiency loss due to partially out of phase field cancellation. That owner should install a new VHF antenna on a forward side of his mast, and put the windex on a bracket above and aft of the masthead, where it's easiest to see too. A LORAN antenna shouldn't be on that masthead at all, as it's ground plane referenced at lower frequencies and can better be closer to the water, such as on a stern pole (mizzen masts make good ones ). Additional types of VHF or UHF whips on a sloop require side brackets to space them. Add a close haul indicator, anemometer, combination light unit (important to have at the masthead running offshore), etc., and a little thought plus a visit to a fabricator who can shear, brake bend, and TIG weld stainless may be needed. Now, I've got a brain teaser where a friend hasn't been able to find a good answer. How do you mount a try color masthead running light on an ocean going cat with a large cross section rotating mast such that it stays properly aligned?
