Thank you for the responses to the "Tuning By Ear" thread. Next time I'll try with the dummy load for sure. Will get the duplexer to a spectrum analyzer soon.
As of today though, I have a more pressing problem. I discovered that the antenna on what will be the new site (water tower) is a custom DB antenna cut for 155.37 inter-city. Argh. The repeater TX will be 147.36 , 147.96 RX SO, I know I need to change antennas. I have a DB-224 and a DB-264A to choose from to put on the water tower at 150 ft fed with 1/2" heliax. One point of note that may be worth mentioning... the antenna will be side-mounted on the North railing of the water tower. When experimenting with the 264 today, I noticed the holes in the mast for the coax are all cut on the same side of the mast! I tried to rotate the elements 90 degrees, but I couldn't seem to make them go that far... especially when the hole was on the opposite side of the mast from the element. What is the deal?? is this a specially-designed antenna to be a uni-directional antenna or is it supposed to be able to go omni? Since the antenna will be on the side, should I use the 264 with the elements all facing the water tower? Is it worth fiddling with the 264, or should I take the 224 off my home tower and use it on the repeater? Thanks for the help, so much! 73 Jeff - N5VAV
