For you more savvy folks out there.....

Question: Will a SENCORE SLM 1453I Analog+Digital Signal Analyzer Meter be what I need to do instrument testing of signal levels? And is it easy to use? Any other suggestions?

Thanks.

I'm returning it today.

That makes sense dattier. Its claim is that it is optimized for DTV which is UHF 480-800Mhz or so and VHF Hi. VHF high Ch. 7-13 is at 175Mhz to 215Mhz, and Ch. 2-6 is even lower at 55-72 and 77-88 MHz.

I wouldnt expect this thing to beat rabbit ears on the VHF Hi, but it does offer some gain on VHF Hi. And forget VHF Lo.

Strong UHF analog performance, also.

EV: when you used the DA-5200, did the antenna need to be moved around frequently? On channels prone to multipath problems and signal-strength fluctuation, how did it fare compared to the Philips MANT510?

I'm also more than a little intrigued at the idea of trying the RCA ANT1500 - particularly with an amp.

I put the Single Classic Bowtie in the corner window that faces North towards the Charleston tower cluster at 45 miles, on the ledge between the upper and lower panes. Picked up all my digitals solid except my 2 weakest channels from Charleston which were acknowledged but no images, including my alternate PBS station on the backside at 23 miles without moving it. Sweet! I knew this was gonna be a pretty good performer, but didnt expect this from it. This Single Bowtie is 13" long and 3" wide at the ends. Curiously, when I amped it, it did significantly poorer.

Seatac, I moved the DA-5200 from one window to the other in the pics to point them in the direction of the Charleston towers and also my secondary PBS at 23 miles. It was a quickie test of the 3 units, and I cant remember exactly how that unit behaved as far as directionality is concerned. But I can check for you.

Im gonna do a mega test once all the units get here, hopefully with a Sencore Analyzer, all at the same time(to eliminate atmospheric variations as much as possible) and with copious notes.

Interesting. I had been curious about the Jensen antenna. Glad I didn't bother with that one. I'm surprised that the coat hangar one didn't perform better. I've seen a lot of posts on the web of people saying how much better the homemade ones are versus the over-the-counter ones. I figured it would work at least as well as the DB2.

Im gonna try a 2nd build on the Coat Hanger Antenna, and I bet it will be much better, Rick, with better materials and different specifications from the How To Build a UHF Antenna thread. I may have just gotten something wrong.

Yeah the Jensen was a dissapointment. Im holding it on the bench, till I test at a second location. I think Im going to do it at my brothers house which is within reach of several broadcast markets and closer towers, for variety. This second location test wont be with the Sencore, Im gonna do that here, since I know the airwaves here better.

Im gonna have to get out my Winegard SS-3000 to refresh my memory on that one, but I think its about right.

I would recommend looking at the Winegard SS-3000 and the RS 1892 UFO, too, given your concerns.

This coathanger did better for me than the youtube. It has a reflector. Using the narrow edge of a 2x4, so you get 4" spacing to the reflector. The one you have already built should do better if you square up the coathangers, they look like they got bumped, one is rotated up and another down, so they lost their spacing. When mine get bumped I see a huge difference in reception. I try to keep the tips of each the same distance apart, and keep an eye out for the gaps between coathangers. If they get off square, it's a one second adjustment. I have a youtube one and also a reflector version like this link below. The reflector did better with multipath, for two channels aiming it backwards helped. It's an amazing little freebie. I appreciate your great collection of antennas.

Thanks TalkingRat. Ive been reading the How to Make a UHF Antenna thread here on the AVSforum and it seems to me that both the reflector and the larger spacing between bow ties are improvements to the design.

What do you think about that?

VHF performance will matter to a lot more people than many realize next year when stations go back to their old channel #'s.

Please definitely add the MANT950. The DB2 and that channel master you mentioned may be great performers, but they are way too unattractive for me to be used inside. (Honestly, for those of us with aggressive HOA's, they might not be options for outside, either.)

That MANT950 screams hang me above a large flat panel or rear projection display.
post #229 of 3314
I have a friend that covered his DB2 with a lampshade material and hung it from a swag chain. The antenna looks like a 60s lighting fixture in his family room. Not too bad at all...

I just bought an RCA ANT806 of that design.  Its UHF performance is fine, but all the transmitters are 8-9 miles from me.

Can't find anything about an ANT701.

Unfortunately, the ANT806 isn't good enough to make up for my TV's weak ATSC tuner ... at least not if I can't find a way to mount it outdoors and connect it from there.  Right now it's feeding a CECB, but I'd like to view HD in HD without popping for an HD receiver (such as a Samsung H260F).

Ill add a couple of those style units, allargon and dattier. The Terk TV-55, Philips MANT950, and one of the RCAs. There seem to be 3 of them, the ANT706, ANT711, and ANT806. Anybody know which one is more commonly available, which ones have been discontinued, etc? I think I saw one at WM, but cant remember the model number.

Allargon, maybe you could use teh 4220 inside its box in the closet.

Channel Master 4220 came in today.

Channel Master CM4220 came in today. It comes fully pre assembled, all you have to do is attach the balun with wing nuts, and it has brass plated steel mounting hardware, u-bolts and pole braces, nuts etc. Galvanized steel makes up most of the unit, plus some plastic, and the reflector is powder coated. The whiskers and feedlines are 8" galvanized steel, which are longer but thinner than the DB2's 6 3/4" aluminum 4mm whiskers.

I tested it down in the TV Room unamped, then took down the DB2 from the roof and mounted the CM 4220 there. I had the Single Classic Bow Tie handy down in the TV Room, so I A/B'ed it with that, and they performed about the same, with it being a dead heat, both unamped.

Early impression are its stronger than the DB2. Windy conditions caused dropouts on the DB2 up on the roof, especially afternoon offshore breezes, while watching BBC World News on Ch. 7 PBS Charleston at 45 miles NE and Ch. 16 alternate PBS at 23 miles SW. Ill check tonight, a breeze is picking up.

Here is a pic of it mounted on the roof attached to a Channel Master 7777 amp and 50 ft of Quad Shield Copper on Steel RG6. We'll see how it goes. Im pretty positive about it being a step up in performance.

If/when you take it down, could you please post a detailed photo of the mounting setup? Thanks.

Will do. Ill take side by side photos with the DB2 up close. I think the Channel Master uses tougher materials, but I like the design of the DB2 better, and its no slouch. Plus I like that the DB2 uses more aluminum and is lighter, although its reflector is coated steel. I like DB2's mount better as well. The CM 4220 attaches to its free floating reflector, the DB2 to a backside aluminum post. Youll be able to see it in the pics, when I post.

Did you get the RS DA-5200 yet?

Here is a pic of the xg91 that I took down. I already disassembled it and its ready to ship. Gonna put it up on ebay. Been up for 8 months or so, excellent shape. Its a great deep fringe antenna. Its just too directional for my situation.

I put the Single Classic Bowtie in the corner window that faces North towards the Charleston tower cluster at 45 miles, on the ledge between the upper and lower panes. Picked up all my digitals solid except my 2 weakest channels from Charleston which were acknowledged but no images, including my alternate PBS station on the backside at 23 miles without moving it. Sweet! I knew this was gonna be a pretty good performer, but didnt expect this from it. This Single Bowtie is 13" long and 3" wide at the ends. Curiously, when I amped it, it did significantly poorer.

EV: my experiences with the Radio Shack 15-234 UHF Outline Bowtie have been fairly good but not totally satisfying. On a couple of stations, it's pulled in amazingly high signal levels. However, in my locations it's prone to pulling in multipath interference and signal fade. My location is a couple of miles from a nearby airport and flight path, and is prone to a lot of multipath inteference. I did like RS' "Single Bowtie", especially for the $4.39 price at RS. Are there tweaks to reduces its sensitivity to interference? Please share your experiences.

In my user experience, the Radio Shack 15-234 UHF Outline Bowtie and RCA ANT110 were pretty close, I'd give a nudge towards the RCA. It generally was a bit more resistant to signal drop out, though overall signal levels were a bit higher on the Single Bowtie than the RCA loop.

Still evaluating the Philips MANT-510, which I believe to be a more dependable suburban indoor antenna (in terms of signal feed stability) than the RS 15-234 UHF Outline Bowtie. My sense is the MANT510 also provides a somewhat more stable signal feed than the RCA ANT110 or Radio Shack 15-1868 (another of my favorites).

Later this summer, I may work with a couple of condo neighbors to set up a rooftop antenna. In the meantime, I'll keep looking at the various indoor antennas discussed here.

Im giving the nudge to the Single Bow Tie. I just got an RCA ANT108, and Im impressed with it. It seems to be fairly well built, nice and tight. And it did pretty well for me but not as well as the single bowtie, but it has rabbit ears for VHF Hi integrated that the Single Bow doesnt, so plus one there. I think your issues with multipath and interence made the RCA's lessor gain an advantage in your situation(not to mention it has rabbit ears for VHF Hi. The MANT510 has a more directional array I think, and even if its not, one side is permanently downwards oriented. I think that is helping you.

I like the 1868 too, even though it doesnt look that way from the list. It the MANT510 and the RCA ANT1500 are tightly packed and I like them all better than the Philips MANT940 and the amped Youtube antenna. Im still working on things, atmospherics are almost certainly skewing my So Far Performance list. I used the Single Bow Tie today, and it didnt do as well, but still pretty good.

Oh, the RCA ANT108, I like it.

As to making the Single Bow Tie better for you, cut out some cardboard from a box wherever you can find one and wrap it in aluminum foil. You can experiment with the dimensions, but Id start out with say 17" x 9". You just made a reflector, which can make your omni or bi directional antenna more directional. Just use it hand held behind the bowtie also hand held, and move it around experiment with it. Id say hold it about 3" to 4" back will be best and parrallel. Aslo, you can use your new reflector with all your other antennas, the RCA ANT110 and the Philips MANT510, etc. Put it between your antenna and the airport(or other source of interference) maybe?

Let us know if you try this and your thoughts and observations.

BTW, I did just that with mine, to check it out today, with one side of the corner reflector off of the xg91. It worked, I got more gain out of the Single Bow Tie and it picked up a couple of channels it was struggling with today.

PS - The RS Single Bow has a Rabbit Ear size plastic clip for mounting, and a smaller one on the other side for mounting to a small wire. Ill mention that in the front page guide.

PPS - Im interested in your experiences too. You have different concerns than me. I dont have much interference out in the boondocks.

PPPS - Im thinking of moving the RS 1868 Delta up above the Philips MANT510 and RCA ANT1500. But maybe Ill just leave it there, till the instruments get broken out.
