Lots of options, that's for sure. Glad to see I'm not the only one making home made digital antennas. Actually a friend made a simple "shoe box" antenna and we were amazed that high quality HD signals were available over the air for free.
Not that guys are competitive or anything
but then 3 of us ended up having a little competition to see who could make the best antenna and get the most stations. We built 3 different designs. I went with the bow tie design, the others a little more complicated. They all do well.
I've used the bow tie one on my boat at various locations, sometimes in locations that you wouldn't expect it to work and at fairly long distances.
I think that some people go for an amplified antenna thinking that it'll pull in stations better but we havn't seen the need to have an amplifer
In the short term I'll be putting the bow tie antenna on a modular aluminum pole mounted to the rear bike rack receiver. I expect that I'll just tidy up the design a little and keep on using it.
At home I actually bought an 8 bay OTA antenna. For $60 bucks I probably couldn't have bought the aluminum pieces. It's beyond fantastic. It feeds two TVs with a stunningly good HD quality. The quality is better than my cable feed. I toggle between the two feeds and people are amazed that such a high quality signal is available over the air for free.
