Help me buy VHF/UHF television antenna? Can't decide!
I'm in zip code 63401
This means that my local off air channels will revert to high VHF next Feb....... channels 7 and 10. Along with few channels that will stay on UHF mainly PBS channel Soooo..... I need a combo high VHF/UHF antenna Compact would be nice for sure I'm looking at these two diff antennas: Channel Master 2016 http://www.summitsource.com/product_...oducts_id=7084 Or the Winegard HD 1080 http://www.summitsource.com/product_...oducts_id=7048 I'm gonna mount the antenna at the peak of my side of the duplex I rent and the towers are all in same direction and 20+ miles northeast of me. I will use a J mast and mount like a satellite dish. Which of these two antennas would YOU go for and why? I'm undecided!! |

I'm undecided!! definitely the HD, anything with HD in the name has to be higher definition than anything else and that must be better than non-HD. |

Compact is NOT an attribute that attends both multi-channel and HDTV. Channel Master 2016 http://www.summitsource.com/product_...oducts_id=7084 22 Active Electronic Antenna Elements indeed. -whew- They may be counting the mast and the transmission line too for all that brings you in gain. Speaking of which, it isn't actually obvious what gain is coming your way with either of these. The quotes are "by gosh and by golly" sort of claims. .................................................. .. They seem to be counting each half of a log periodit element as a separate element. Ditto for each side of a corner reflector. Tam/WB2TT |

Actually the 2016 has some advantages. Although the other will have higher
UHF gain, it has no gain and no protection against multipath on the VHF frequencies. The 2016 will be flatter with a cleaner front to back pattern (although lower gain). If you have no hills or tall buildings and the source is on a single tower, then the other may be better. Depending on your terrain. If there are hills or tall buildings you will want a sharper, higher gain antenna then add attenuators or tilt compensation to reduce the reflections. Saving $20 or $40 can wind up a waste of money. As always, your mileage may vary due to terrain, location and ERP of the transmitters. The real answer is to look at what others are using and see what the picture is like. If they suck on Analog, you may have dropouts on DTV. Anyway, its all just commercial liberal commie brainwashing and propaganda. What channel has the Rifleman and Andy Griffith still?

Yeah I'm kinda leaning towards the 2016. But can you explain why the 1080 has no protection from multi-path? Are you saying that the 2016 is far more "directional" than the 1080?

Yes I do have on bi brick two story building right in front of me in direction antenna must be pointed. sigh Anyway, its all just commercial liberal commie brainwashing and propaganda. What channel has the Rifleman and Andy Griffith still? Aint THAT the truth!! I've seriously thought abt giving up broadcast TV and just watching everything off the Internet such as hulu.com. Serious!! At least on hulu.com I can still watch Andy Griffith, twilight zone, etc!! |

But can you explain why the 1080 has no protection from multi-path? Are you saying that the 2016 is far more "directional" than the 1080? While the 1080 UHF is fairly sharp with some potential gain, the VHF elements seem to be little more than "rabbit ears" - In fact it is a swept dipole, so will be bi-directional and easily pick up reflections from behind and around you.. Sweeping the elements has the effect of allowing the elements to be better matched at odd multiples. The 2016 will have a broad front lobe (less directional) have good bandwidth, and signals from behind will be blockedfor UHF and VHF. It's drawback will be ice and wind loading. Still I would have really liked a 1080 with a few (like 2 or 3) more dipoles out behind for a better protection against reflections . I scratch my head to see a 15 db corner reflector UHF and 0db VHF dipole together. As if the VHF were so strong it was an afterthought. I have a wee bit more than that (same UHF but with 7 VHF dipoles) with some elevation looking at a mountain site about 75 miles away. My elevation just barely allows the signal to clear a pass 10 miles away and I have perfect Anolog reception while neighbors who are one stop closer struggle for signal. In fact, I have used the antenna for 2m SSB with 10 watts. Don't forget about good quality RG-6 for your feedline, and keep it as short as possible (but it is better to get the antenna higher to clear the next door building). This is more critical for UHF stations (perhaps why 1080 went that way). Depending on your terrain. If there are hills or tall buildings you will want a sharper, higher gain antenna then add attenuators or tilt compensation to reduce the reflections. Saving $20 or $40 can wind up a waste of money. Yes I do have on bi brick two story building right in front of me in direction antenna must be pointed. sigh That is a complication but not if your antenna can just see across the roof of the other building, then it can actually help. If the main signal source is reduced, reflections will be more pronounced. The problem with digital, all you have is a bar graph. Reception problems are totally masked. The reception problems that degrade Analog still degrade Digital, you just can't see it. I have seen situations where there is lots of signal on the bar graph, but the picture still breaks up because of distortion of the signal. So while Analog is still there, get your antenna aligned and locked down and hope no one builds another building. Sometiimes pointing the antenna at a tall building or mountain will give a better signal because all stations are bouncing from that building.. If you can stand on your roof with binocculars and see the broadcasting site, and there are no 12-100 story buildings or mountains around, put your antenna there and be done with it. Keep in mind that if you find yourself running 75 feet of coax, it would be like putting up an $80 antenna just to shorten the coax to 35 feet. Anyway, its all just commercial liberal commie brainwashing and propaganda. What channel has the Rifleman and Andy Griffith still? Aint THAT the truth!!

Sweeping the elements has the effect of allowing the elements to be better matched at odd multiples. . . What the bending of elements does is to align the lobes broadside at the frequencies at which the elements are approximately 3/2 wavelengths long (that is, at about three times the fundamental half wavelength frequency). Without bending, a 3/2 wave element has lobes which aren't broadside. Bending it brings these to point broadside, resulting in a an approximately bidirectional pattern. It's the shortest "vee beam" type antenna, which extends this idea by decreasing the angle to maintain alignment as the dipoles get longer. The bending used in TV antennas has little effect on the impedance match. Roy Lewallen, W7EL |

Ok thanks for that explanation! I am in fact a general class ham but haven't operated for years....no equip either. And am def not an antenna expert. So its nice to get some "science" on why one antenna is better than another when it comes to DTV! Thanks! Don't forget about good quality RG-6 for your feedline, and keep it as short as possible (but it is better to get the antenna higher to clear the next door building). This is more critical for UHF stations (perhaps why 1080 went that way). For sure! Matter of fact I see some good prices on Philips RG6 at local Walmart Now I just gotta find a J mount for a sat dish as that is how I'm mounting the CM 2016 when I get one. I will install on the SIDE of a roof peak.... the fascia.... just like you would a sat dish Gotta figure some way to get up there tho as no ladders big enough. Guess I can borrow one from a friend |
