I enjoy drawing and building antenna's. The picture attached [attachment=0:4uxkpmle]DSC04822_1.jpg[/attachment:4uxkpmle]shows a modification done on a LP5 from TITANEX. On the 20 meter band it had a bad F/B gain. I added a fishing stick in carbon to maintain a reflector behind de antenna. It's designed similar to the reflector for 20 meter from the TITANEX LP-15 and calculated with the program MMANA-GAL. Before modif: Gain 6.78 dBi, F/B 3.96 db. After modif: Gain 8.63 dBi, F/B 17.47 db! I have much less QRM and I can communicate with much more station on 20 meter sins I did this. I can give you more details about the modif if your interested. 73 on7tw.1@gmail.com
