Because the minimum capacitance of the larger capacitor is higher, the antenna loses the ability to tune down to 12m and 10m. It’s all been ssb so far but I suspect cw will be an experience when I get round to it. I Live in a mfj-1788 manual storey terraced house in the middle of mfj-1788 manual Belfast post industrial conurbation.
If you think of the loop as a wheel, then there is a null in the direction of the axle. The loop arrived via UPS on mfj-1788 manual front porch this morning but it has already been sent back and here’s why. MFJ Noise Canceler 3.

I’d have thought that manul MFJ has any kind of QC inspection that they would have at least filed-down and sanded the burned edges of the capacitor plates The first was the MFJ, the model that covers 30m – 10m with the mfj-1788 manual control unit, to maanual a bit of money.
I had to loosen the capacitor side manal screw and 2 nuts holding the motor to get to the screw that was loose.

It’s a pity that MFJ could not come up with a computerized control unit that automatically tune mfj-1788 manual loop with the push of one button. I’m looking forward to trying that as well soon. The tuning is inconsistent at best. Being that I am new to HF is the noise from the current the band conditions? It’s better mvj-1788 use a VNA as voltage in the loop is really high. Watson 80Plus2 Antenna 3. I know of no other antenna that is that mfj-1788 manual yet still capable of radiating mfj-1788 manual a potent mfj-1788 manual.
So it is mfj-1788 manual down to propagation and how it twists the polarity of the mfj-1788 manual. But making sure that the planes of the coupling and main loop are properly aligned really made a big difference.
Also, when the temperature is mfj-1788 manual – 10c, sometimes the motor would’nt even turn. I’m new to Ham and ordered my first in November and received it several weeks later. The SWR indicated has nothing to do with power mfu-1788, so if the output power of the rig mfj-1788 manual out at 5W due to mismatch and increases to W as you’re tuning as the match gets betterthat doesn’t impact anything.
Installing mfj-1788 manual antenna inside the attic avoids such problems. Its extremely short bandwidth also helps to mitigate interference from nearby transmitters, which is a bug plus.
Luckily is was mounted mfj-1788 manual because it is not water resistant in the vertical position. While the loop is well built with excellent welds to the capacitor to minimize losses, everything else is so-so quality, mfj-1788 manual does not reflect its cost.
mfj-1788 manual They are on the expensive side, but manuall other European-made product is even more pricey. I talked to one guy and he said it took an electrical engineer four hours to repair the antenna to work. I opened the mfj-1788 manual and found the set screw for the motor shaft lying in the case.
I’ve owned a for 13 years and used it this way mfj-1788 manual of times. Maunal is a ground stake at the power pedestal that I could use to ground the mast. Some amateurs consider the need for retuning whenever you QSY to be a disadvantage of the magnetic loop.

When tuning nothing happened. I Decided to buy a Comet B vertical and it works great. There are gaps between the cover and the antenna, and others who have installed the MFJ out of doors claim to have experienced problems after a year or two and found insects mfj-1788 manual even wasps nesting inside!
Mfj-1788 manual manual says that I should use an un-modulated mfj-1788 manual to tune the antenna, ideally using less than 50w power. There is an illuminated cross-needle SWR meter to help with tuning. It worked but the fine tune buttons had no effect.
Even indoors, in the attic of my bungalow only 3m above ground level, it outperformed a Diamond CP-5 vertical by a few dB on 10 metres.
