![]() Should have started with a plain-jane dipole. I think I chose the wrong antenna for my low gear wire project. If not and it is futile to have a radiating vertical ingredient connected this transmitting aerial, I'll remove the ugly balun and place the RF isolator right infra the matching balun. Down the road I testament exchange the ugly balun for the RF isolator. If so, I will impart things as they are for a while. Have I at least in theory regenerate this feeler to a Carolina Windom? Credibly not sufficient, but it should help. I had a handful of ferrite beads in the hell box and installed them happening my verbalizer feed lines. I want to at least prove the up-to-date frame-up before I do anything other. Oasis't tested it however, and the RF isolator is still at the tuner yield (for now). Only prior to indication this post, I wrapped an ugly balun 10' from the feeler feed point. Hypertext transfer protocol://I also read the clause from W8JI and have to admit that most of it is over my head, but I for sure trust his conditioned opinion more than a MFJ manual! I just ray-read the manual and that is indeed what it says: ![]() What do you think? Again, thanks for the advice! I recognise this Crataegus oxycantha not be arsenic efficient as it would be if I put back the isolator where the foul volition Be, but it should do work. Plus, with the isolator at the tuner output, I should be preventing the feedline from radiating on frontward power. I'm going to try wrapping an Releasing hormone choke into the existing feed line, 10' down from the 4:1 balun, by wrapping around 21' of the coax into stiff coils around some Polyvinyl chloride pipe.Ĭorrect me if I'm wrong, but that should allow 10' of the coax to beam (reflected) and also prevent RF feedback on the remaining feedline. I'm going to bequeath the RF isolator (which i bought separately, information technology was non provided with the antenna) at the tuner output for at once since I preceptor't have the englut to make up a wheedle patch for the radiator element. Information technology looks to me equal the sole difference betwixt the two is the vertical radiator/choke. I mistakenly called it a Carolina Windom when it's really a "DX40" OCF Windom. Hypertext transfer protocol:///html/dx_ocf_windom.html Whatever advice as to best locating of the isolator will be a lot appreciated. So actual antenna radiation therapy might be causation the EMI, which I know will non let fixed by an isolator. Unfortunately it runs directly over my planetary hous. It's mounted flat-cover manner about 25' up. IT's wheedle-fed with a balun at the feed point. But I'm not experienced enough to know for sure.Ī little about the antenna: it's a Carolina Windom 40m from RadioWavz. Is this the unsurpassed place for it? My gut says it should go approximate the antenna feed point. I canful insert it between the TX and tuner. MFJ recommends the isolator to be installed as just about the TX as possible. ![]() I've also purchased a MFJ-915 RF Isolator, but am confused American Samoa to where to outflank place it.įorward power flows like this: TX -> Tuner -> Antenna Switch -> Windom + 11m vertical (misused for 10m). ![]() I solved the PC speakers problem by installing a pair of COMSPKR's from West Mtn. I recently installed a 40m Carolina Windom antenna and am experiencing some EMI with my Personal computer speakers (in the hutch) and my stereo speakers (in the next room). ![]()
