The antenna that Voom uses, the Channel Master StealthAntenna, is one of the aesthetically best looking antennas available. Not bad reception to boot... If it weren't raining, I'd go snap a pic of mine, but, wouldn't do much for you right now.
The Stealth is actually not a bad looking Ant. In my area though a more directional Ant without the amp is working better than the Stealth did with the amp. So I replaced the Stealth with a directional ant...which still doesnt look all that bad. Do yourself a favor, go to radio shack and buy yourself a tripod mount and a 5ft mast. The higher you get the Stealth the better. The 5 ft masts are great at radio shack because you can add to it anytime you want by buying another 5ft mast...they connect together ...up we go!!!!!
FWIW, I moved my Stealth antenna from an exterior roof mount to inside my attic. This actually improved my signal strength (the original location was not at all optimal). If you have an attic then you have another alternative.
