I am getting Voom installed on the 22nd and have a couple questions about the OTA antenna they used. Currently I have a RadioShack UHF 2160 antenna on my roof. It currently can get all the OTA channels possible in my area. There is no amp installed currently. I was wondering if the antenna provided by Voom is better than the one I currently have? Is the antenna ampd? Finally my antenna is always pole mounted. Can the antenna Voom provides be pole mounted or only bolted into a roof. Thanks!
