My last couple of posts have been dealing with extending the bandwidth of my MFJ 1788 loop antenna. With the loop the lower the SWR the more bandwidth I have before I have to retune the loop. Up to this point I have tried moving the antenna ALL over my balcony and the best SWR at that point was at best 1.6 with the loop in the horizontal position. I then gave the loop a go in the vertical position something I had never done before. I was surprised that the loop had a better SWR, I was able to get it down to 1.4 SWR. One last suggestion given to me was to adjust the internal 10 gauge coupling loop. Today I took the section of the cover off that exposed this coupling loop and moulded the loop from it's "0" shape to more like an egg shape. with doing this I was able to lower the SWR do 1.2 to 1.3 depending on the band I was on.
