Mfj loop antenna in attic.

I went to my friends house to check out his setup and get him up and running on some hf digital modes. Especially on 15 and 10 meters. The noise floor is about 10dbm higher on the attic located mfj loop vs the outside wellbrook. Get both low angle radiation for excellent dx and high angel.

I know that a compact loop is still considered a compromise antenna especially in an attic but this surprises me especially with the super low swr of the mag loop once its tuned in. Even if it is mostly used by ham radio operators to solve problems while transmitting the mfj 931 should also work for a receive only purpose. The mfj 1836h cobweb antenna for your attic. But the performance on 20 meters does not seem nearly as good as my dipole.

Mfj has created a set of 1 2 wave dipole antennas folded into a square sort of a cobweb antenna. Installing the antenna inside the attic avoids such problems. The mfj 931 could potentially be used a tuned counterpoise for your attic shortwave antenna. They are the mfj 1836 229 95 that handles power up to 300 w and the mfj 1836h 259 95 that handles up to 1 5 kw.

A lot of hams are struggling in an hoa with antennas o. 8 responses to a brief overview of my mfj 1788 loop antenna. Michigan building code attic access. However the snr is so much better with the mfj loop that it almost always discounting virtual ties gets a better receive signal.

The tuning is fairly sharp but is not a big deal for me as i operate mostly jt65 and jt9 these days and the sub band for these modes is only about 4khz. I have each loop mounted on the same model ar 500 rotator with bearing degrees programmed. I use an mfj loop antenna on 40 through 15 meters in my garage attic antenna farm restricted subdivision. I recently got a mfj 1788 loop antenna also installed in the attic.

Mfjs tiny 36 inch diameter loop antenna lets you operate 15 through 40 meters continuously including the warc bands ideal for limited space apartments small lots motor homes attics or mobile homes enjoy both dx and local contacts mounted vertically. 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 or even wasps nesting inside. I would estimate that its performance is about as good as an outdoor dipole.
