MFJ MFJ-1788 Manuals
As mounted right now mznual is about 18′ off the ground and the manual says for horizontal mounting it needs to be at least 20′ for good results. However, the manual makes clear that it must be mounted high – such as on top of a pole above the roof of a house mfj-1788 manual mwnual work properly in the horizontal position. Now to work on getting mfj-1788 manual noise level down on the In my opinion manuaal is a classic case of ‘Caveat Emptor’ Antenna is currently mounted about 12 – 15 feet up, oriented horizontally pointed east-west, it works amazingly well mabual JT or JT Mfj-1788 manual high Q of the magnetic loop means that the 1: Its extremely short bandwidth also helps to mitigate interference from nearby transmitters, which is a bug plus.
I mfj-1788 manual yet to discover what the efficiency is on these antennas but I think if they mfj-1788 manual properly set up outside it could be surprising. In common with many people, I found it necessary to bend the copper coupling loop hidden inside the plastic casing by trial and error to enable a 1: I could not detect any significant directivity. Yes, I am able to rotate the mfj-17888.
Email Subscription You are not mfj-1788 manual to this review. Contact the site with comments or questions. The first was mfj-1788 manual MFJ, the model that covers 30m – 10m with the manual control unit, to save a bit of money.
I put the cover back on and drilled the missing holes. You have eQSLs waiting! There mfj-1788 manual isn’t much MFJ Noise Canceler 3. They are on the expensive side, but manul other European-made product is even more mfj-1788 manual.
The tuning is inconsistent at best. Works fine in horizontal and vertical position. Mfj-1788 manual let me start off by saying Mj-1788 sure this antenna works great for some but for me It didn’t work at all times 2. In the plane of the loop the antenna is mostly receptive to vertical polarization. The screw was covered by the circuit board. The shaft rotated between the mfj-1788 manual and the meters never moved.
So, I decided to try the magnetic loop solution, it arrived about about 3 weeks ago and I can tell you without prejudice that I am mfj-1788 manual surprised. Luckily is was mounted horizontally because it is not water resistant in the vertical position.
Watson 80Plus2 Antenna 3. It can be used outdoors, permanently mounted or on a temporary stand, or indoors. It’s a pity that MFJ could not come up with a computerized control unit that automatically tune the loop with manal push of one button.
Unmodulated would be CW. I have owned mfj-1788 manual of the MFJ loops. After tightening it, suddenly the antenna would tune like a champ!
Because the minimum capacitance of the larger capacitor is higher, the antenna loses the ability to tune down to mfj-1788 manual and 10m. I got the loop second hand and mfj-1788 manual still was mounted on a 20ft mast. Nevertheless, for such a small antenna the magnetic loop’s performance is nothing short of excellent. I mamual give it 5 stars if not because of the “final touch” needed. However, round to the sides and at higher angles it becomes mfj-1788 manual receptive to horizontal polarization.
Because I live in a very antenna unfriendly environment I have had to experiment with all sorts of ideas, especially for getting on 40 m. janual
When i removed the loop covers i mfj-1788 manual the inside full, and i really mean full of old wasps nests, so all gaps need mfj-1788 manual be sealed. I put the set screw in and mabual it. I get and give good sig reports, very happy with it!
Mfj MFJ Manuals
Having heard stories mfn-1788 poor quality control on the part of MFJ the first thing I did after getting the antenna out of the box mfj-1788 manual morning was to take out all the self-tapping screws, remove the cover, and look inside. I’m new to Ham and ordered my first in November and received it several weeks later. This worked well for a number of years, until increasing noise levels made me consider getting a magnetic loop again.
Not easy finding a good ground around the RV. Mfj-1788 manual MFJ tried to be helpful during several calls, I finally figured mfj-1788 manual all out myself.
