We ended up with 23 good signals/channels, but once in a while a few of them go intermittent, given our "two edged" refracted signals, lots of rain, helicopters causing phasing effects, and wind damage to the source tower.
* The above is a drawing of my small exploratory antenna (on a long pole), which was first to find out if my current problems were due to interference or parasitic oscillations in our old, tiny, amplified, outdoor antenna. I walked our property to determine if location and height made much of a difference. The signals were definitely stronger with elevation and distance away from the house.
Most of today's TV signals are in the lower end of the old UHF band, for which antennas can be small affairs (compared to the old VHF monsters --the kind that housing associations would try to outlaw with their CC&Rs). Sometimes all you need is that loop of wire --properly fed into your down lead cable.
* Gosh: but I got some good clean signals --using just a 9 inch diameter loop of 1/16 inch bronze welding rod, a standard 75 to 300 ohm balun/transformer (that's it near the loop), a well anchored 8 foot 2x4 (for to over-build a non-conductive mast, since I ended up almost within falling distance of our home's electric power cables), 25 feet of old fashioned RG-59 cable (which I had on hand, and RG-59 is only supposed to be about a decibel worse than RG-6 for such a short run). With two 1 inch pan head sheet metal screws to secure the antenna and balun to the end of my wooden mast, it worked. (A 9 inch diameter loop is about right for low-end UHF channels and gives fair capture area, but a directional commercial antenna is always much better for minimizing reflected ghost signals. That's what we ended up going to, on account of a big sand dune being in the way of a direct signal path.)
* Dabs of black RTV/silicon rubber over the screws
and to seal the RG-59 connector to the (outside rated) balun against the
weather is a good idea.
* Our GE brand, "70 mile", VHF/UHF antenna is a puny looking thing, compared to the old Winegard and Channel Master antennas I use to install some 30+ years ago. It cost $50 locally, which included a good J-mount and a built in balun. That brought back good reception on our 4 public television channels during rainfalls.
* Again: all of our channels are "one edge" or "two edge" refracted reception here, meaning the signal has to climb and bend over interfering terrain (mainly: the big sand dune).
* When our local Radio Shack died I got a deal on 25 feet of quad shielded RG-6 down lead cable, so I broke down and replaced the old RG-59 --not expecting much difference --but the station count went up to 23! (Since the down lead is rather short, a low noise pre-amp probably wouldn't help much --unless it happened to be superior to our TV set's front end/tuner.)
** But after I got back our PBS channels, we got to watch weeks of infernal fundraising! (Those shameless beggars want your credit card number, a direct route to your bank account, want your car, want to be in your will --sheeesh!)
* IMHO, the best resource for guestimating what channels you can get remains "TV Fool". All the others I've tried were useless, perhaps due to their out-of-date data basis.
* Charter^ was charging nearly $55/month here for stand-alone Internet access, and nearly $30 (each) if combined with two other services (phone and Internet, at the same rates) --for about $90/month total. Presumably, each of the other services, alone, take that higher rate. So that's what we we're saving by troubling to put up an antenna --and every month. We trouble to access the Internet via free public WiFi --for news, email, and maintaining our 40+ web pages --which are all freely hosted at NeoCities (for which, we freely donate). For that 3rd service of telephone, we use a Tracfone, which costs us about $10/month --depending on use.
We bought our old CDMA band, flip type cell phone for
something like $10 to $15, since CDMA technology seems to work everywhere
--even here behind the big dune, but you can't get that type anymore. Hopefully,
you have good 2G, 3G, 4G service where you live, good broadcast TV and
plenty of public WiFi signal choices.
Be sure that you use a friend's private (password secured) WiFi when buying stuff or doing banking. (We do zero banking via the Internet.)
