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!
