You can modify the DB-224 antenna to bring it down from the 155 mHz area to the ham band by adding two inches of tubing to each end of each element. I use tubing from a scrapped TV antenna and flatten it where I wrap it around the bottom and top of each loop and secure it with a screw through the flattened tubing. I then measure the length projecting from the end of the loop and cut it back to two inches.
I have not had to modify the harness to get satisfactory operation in the ham band. 73 - Jim W5ZIT -----Original Message----- From: [EMAIL PROTECTED] To: [email protected] Sent: Tue, 24 Apr 2007 9:38 PM Subject: [Repeater-Builder] DB-264A or DB-224 ? 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. ________________________________________________________________________ Check Out the new free AIM(R) Mail -- 2 GB of storage and industry-leading spam and email virus protection.
