    With the change to DTV
    we ended up with "Virtual" Channels what are these?

    The "real" channels are the channels the TV stations are using to transmit on. Back before HDTV, the channel number told us what frequencies the TV station was using. We became so used to the channel number being the be-all and end-all for a TV station that the FCC or the broadcasters (TV stations) thought we'd get really confused if all of a sudden ABC Ch. 7 changed to ABC Ch. 32. ...

    Let’s go over a few things about dipole antennas that I have picked up while being an amateur radio operator. I will start with what is known and go from there. I will then apply this to over-the-air TV and simple Bow Tie TV antennas.

    A word of warning: One of the things I learned when I was a boy was that if you have an idea, give it a try, and see what happens. In school, I learned that sometimes what you don't know can kill you (think about Madam Curie and radiation). So, please think about what you're going to try and see if you can find any danger in it. Safety is ...

    This antenna was an extension of an idea I had back in 2002, and had an article published about the precursor antenna in Popular Communications, in January 2003: "Phil's Easy Way To Improve Your UHF TV Reception."

    The next article published shows this antenna completely as I still use it today. This article was published in Popular Communications, February 2013, pp 10-16 ...

    I was given an antenna by a family member who didn't want it any longer: It is the RCA, ANT 140. The label said: Thomson Consumer Electronics, Deptford NJ 08096-2088. I don't know who the real manufacturer was, but it was made in China.

    Looking on the Internet I found:
    THOMSON Consumer Electronics Inc./RCA
    10330 N Meridian St.
    Indianapolis, IN 46290-1024
    P: 317-587-3000
    F: 317-587-6765

    I don't know if they are one and the same company who designed this small amplified indoor TV-FM antenna. My guess is that it was Thomson that designed and had it manufactured. ...

    The location of the antenna is one of the most important elements of signal reception for radio waves. DTV is using the same frequencies for the stations as before except that channels below 7 are no longer in use. Those stations had to move to higher frequencies. An example of this is Washington’s WRC, Channel 4, which is now using the frequencies that had been for channel ...

    This article originally appeared in 2013 but has been extensively updated.

    I will try to give some basic information about what each of these things is, when to use them, and when not to use them.

    Balun is a contraction of two words, Balanced and Unbalanced, and it refers to the type of antenna to the type of feed-line. An example of a balanced antenna is the full-wave loop, the dipole, and the bowtie antenna. An example of an unbalanced antenna is the long wire antenna, or even a non-center fed dipole ...

    Earlier this month, March 2016, a fellow ham radio operator who is also interested in UHF TV antennas, contacted me to tell about his experiments with his Pennyloop antenna design. His site is, http://www.pennyloopdesigns.com and you can buy his plans for less than $5.

    For those of you who do not know, a pennyloop antenna is an antenna based on a full wave loop antenna. It is basically a single loop antenna that is made out of some conducting material that starts out as slightly longer in length than the longest wavelength you want to receive. It is then bent into a loop and is ...

    If you go online to any number of TV sites (TVFool, antennaweb, or hdtvprimer), you will be told which antenna has better gain and/or which antenna should work in your area.

    Gain is not the entire picture when dealing with DTV signals. There are various means of interference and even if one antenna has lower gain, it could get a particular station, or stations, better than one with clearly better gain if it has better rejection of some particular type of interference causing problems with some of the stations in your area or, in particular, at your location.

    With the old analog signal, we could actually see various forms of interference, such as reflections, weak signals, co-channel ...

    I was looking at the "Understanding CEA Antenna Marks for Outdoor Antennas" page on the Solid Signal site, located here: Understanding CEA Antenna Marks for Indoor/Outdoor TV Antennas
    when I read what seemed to me to be the statement that the only way to get the TV stations which are very far away is with a medium or large directional antenna with a pre-amp.

    I found it a bit disconcerting to see what I thought was the opposite point of view from my own. My "point of view" is based on best engineering practices and was learned in college and is expressed in numerous articles on the subject, many of which are on the web today.

    To try to clarify what CEA was recommending, I went to their web ...

    Back in the winter of 2013-14, we had some very big ice storms here in the Washington, D.C. / Baltimore area, which took out a large number of branches and a few trees as well.

    The next spring we noticed that the TV signals from Washington, D.C., did not disappear, after the leaves came out on all the trees while using our attic antennas.

    This was a very pleasant surprise and it took me a few weeks of testing to finally figure out what ...
