We use a local Comcast cable affiliate. Over the past few years rates have gone from $40/month with no box needed for most channels to about $160/month (+$50/month for Internet - and we don't need super-speed - we have an old slow modem and router that can stream video without much extra leftover), with boxes needed for all 3 TVs. They don't charge what they say they will over the phone, and they charge us for equipment we don't have. They keep promising to fix that, but they just hide it - it's not on the paper bill, you have to look for our equipment lists on the Internet connection. (Comcast delivers very good service and lots of channels. Most people are willing to pay for good service. Why annoy customers with broken promises and mischarges if you can deliver a quality product? Oh well.) I am curious to see how good local OTA TV reception we could get from an antenna in the attic. I'm also curious to know whether it is likely that we get away with putting an ordinary Dish or DirectTV antenna in the attic. My OTA antenna is an old Shakespeare Seawatch 2030 (round, omnidirectional, about 14" diameter) antenna. It could go outdoors, since it was designed for marine use, but that would mean someone would have to go up on the roof, and we would need to run grounding wires in places that would force us to dig up the paved driveway. My landlord is a retired electrician, but says he is too old to go on the roof. 1. The antenna is Pre-HD. Can it handle the all HD channels? I've already tried it in a second story room with a TV, and it gets about 10 or 15 channels - but reception by channel various with location; I think it needs to be higher up. (It gets about 30 or 40 QAM channels when connected directly to the cable without a box - I wonder whether we would still get all the QAM channels if we just got "basic cable" service - but anyway, the frequencies and subchannels keep changing, and Comcast doesn't publish QAM info, so that may not be a good option.) 2. We have a slanted tar panel roof, tacked on with nails, and the homes around us are the same height as ours. Would OTA and satellite antennae do about as well in the attic as on the rooftop? 3. We tried to look up whether it needs to be grounded. If it needs grounding it can't go in the attic, because code requires that grounded antennae be on the edge of the roof and that the wire from the antenna to the ground follow a straight line path (or something like that - I'm not the electrician). As near as we can figure out, from the codebook and from Internet sources, we only need grounding to meet code if the antenna is on a mast. My intention is to put it on the attic floor, so no mast is needed. Hence no grounding is needed. We think. Does that sound right? (The National Electric Code is a complex document, with lots of exceptions, so my electrician may have missed something.) 4. Regardless of code, is it especially unsafe to put an ungrounded antenna in the attic? We don't have such a large number of lightning storms (we live near DC) that most houses get hit by lightning. But we do have lightning storms a large fraction of summer days, so it isn't, and we know of at least one home whose aluminum siding was hit by lightning a few miles away. Would an antenna in the attic be particularly likely to attract lightning?
