It was only necessary to change the antenna. This involved removing the existing assembly, install the support pole and the dual dipoles that make up the antenna. The pole was positioned to improve signals to South, West and North filling in the gaps of VK5RMG, VK5RNC and VK5RKN.<\/p>\n<p>The antenna tested very well and has resulted in much improved signals in the Millicent area with Tom, Lyndon and John reporting large improvements.\u00a0 I believe that Jack will also see improvements at Southend. Signals are down in Mt Gambier which is not surprising as the leg of the tower will be masking in that direction.\u00a0 &#8220;Good signals to Kingston&#8221; reports Tony VK5ZAI<\/p>\n<p>\u00a0<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"400\" height=\"533\" src=\"https:\/\/serg.org.au\/wp-content\/uploads\/2025\/08\/Happy-repeater-coord_1.jpg\" alt=\"\" class=\"wp-image-7558\" srcset=\"https:\/\/serg.org.au\/wp-content\/uploads\/2025\/08\/Happy-repeater-coord_1.jpg 400w, https:\/\/serg.org.au\/wp-content\/uploads\/2025\/08\/Happy-repeater-coord_1-225x300.jpg 225w\" sizes=\"auto, (max-width: 400px) 85vw, 400px\" \/><figcaption class=\"wp-element-caption\">A happy repeater coodinator, no hard hat so sheltering<\/figcaption><\/figure>\n<\/div><\/div>\n<\/div>\n\n\n ","protected":false},"excerpt":{"rendered":"<p>On Saturday 9th August there was a working bee at Mt Graham to replace the 2M antenna.
