That information is for TV broadcasting, it has nothing to do with "broadband".

I posted on this thread to simply state there are different ways to combine antennas, that had not been mentioned. I have no idea what the OP is trying to do, or talking about.
Rabbit 73 I am very familiar with 4nec2 Antenna Sims by holl_ands.
I have spent hours looking at his work, and try to recreate some of the models into working antennas. Everything you posted in your reply matches my current understanding of antenna stacking.
ADTech your post are always welcome, and reflect knowledge of antenna design, and signal propagation.
As I reread this thread it looks more like user name is asking about horizontal verses vertical stacking of horizontally polarized antennas.
Steve

Rf STEVe look's like you are way in OVER YOUR HEAD!!! So GIV if UP
And for get about them wind sails,and get a 91xg!lol
And trying too sell junk!!OP has spoken!! Of a channel master amp??
And wasting everyone'S time lol.

I solved my reception problems years ago. The 91xg would be a poor antenna choice for my location.
I've only been building and, installing both commercial built, and home brew antennas for about 50 years

B,tong and you wish 50 Years.lol that's all I know is that with my 150ft tower receive of channel's 1500miles away and don't forget my inverted v. ham Radio station antenna.
And do you wont want to sell the 1960,antenna ?
Well good luck but it sounds like you don't know what you are doing with outdoor tv antenna'S ,becuse the 91XG,is best ANTENNA you can buy with a narrow beam pattern
If you don't know how to use the 91,that's the kind of tock you get out of someone
That doesn't know how to use a antennas Direct 91XG,? 50,year's of ANTENNAs to
Funny stop tocking bs,and the solid signal HDB 91,with IT'S90, beam with pattern.
Works well with a channel master 7777,AMP if you're tv,Broadcasting TOWER are in a v pattern you don't need a rotor if the ANTENNA is pointed right.away frum the strongest
Tower's and more pointed tord the far away tower's works quite well and no over load"S
If you know how an ANTENNA work's you should have no problems with RECeive of BROADCASTING channel's, of 1500miles away,lol,

Where are the moderators? The forum's signal is really starting to get overwhelmed by Nascarken's noise.

Boy for some one hoo has just became a member needs to go get a real antenna set-up
And Steve need too RECEIVE and do the same thing get a real antenna set-up too.
Lol 50 years of ANTENNAs instilling lol

This thread is about stacking antennas. Most of the known knowledge on the subject was expressed quite early in the thread.
I will only once more take this thread off topic . 53 years ago I was installing long wire, and dipole antennas in my parents attic, and some times outside.
I’ve wound enamel coated wire around toilet paper tubes to build cats whisker Chrystal radios, and I have used the local oscillator off one radio as BFO (beat frequency oscillator) on an other to receive SSB . When my parents could not afford to to buy me a state of the art receiver with a BFO or product detector.
I’ve been around radio, and TV antennas for a few days, but I do not have a closed mind. I’m still learning.

Yes heath kit one of the best know how ham Radio works
And why should you have a closed mind?share what you
Have done I am all ears,and you know that I am going too get a cold one out of the frige!
And smoke some bud,and I am all ears and yes Rf is a good long topic to tock about
Whether it's radio or television Rf,it's FUN to mess around with stagger stacked hi band
Vhf outdoor tv antennas,CQ CQ CQ DX,Hello can you hear me know?
Long wire &what MHZ??And VFO!!I
???

Recently I changed the coax cables and now can pick-up 2 additional channels(69 and 39 are weak). But other channels are now about 10% stronger. I experienced this situation before. Why does changing the coax cables change the signal strength?

There are a number of possibilities why new coax improves signal strength:

- Better quality coax (e.g., RG-6 is better than RG-59, it has a larger center conductor
- Better or tighter connectors and connections
- Crimps in the old cable
- If old cable was outdoors and weathers (or with lots of sun-exposure) it may have deteriorated
- Water, heat or stomping damage to old cable
- Etc.

Rg6??
 

Yes 18gage SOLiD copper,RG6,& 11,work very well!!!

Although I can't offer you any help with your problem, the red sentence intrigues me.

I used two Zenith converters from 2009 up until a couple of years ago when I bought new TVs. The converters worked great, especially the signal tester. My new TVs also have signal testers but are kinda lame in comparison.

Do you have it hooked up permanently, and if so, can you elaborate on how you did it? (If you just wired it up temporarily to test the signals then I know how to do that). Any of you gurus are certainly welcome to answer my question also.

Anybody know if there is any kind of inexpensive signal tester one can buy?

TIA!

You can make one from the Winegard SensarPro RV signal strength meter. See R. Ross's review on the product on Amazon for instructions. Around $80 for the components, which include the SensarPro, a project box, battery pack, and a DC blocker. I made one and it works well. Results are commensurate to an actual TV with signal strength meter.

However, for not too much more money, you can buy a portable TV such as the RCA DPTM70R, which has a decent signal strength indicator (signal strength rated 1-5, if i remember correctly) plus you can watch it!

Wow, I checked that out and started reading that guy's post and what he did. But into the second or third paragraph I realized this was way over my head. I guess I'll just leave things alone.

Wiring in a third TV just to check signals isn't something I want to do either.

But thanks for the reply anyway. :D

Then the only choice left for you is a used digital to analog converter box made 10 years ago. I liked the Apex DT502 that had two signal bars, one for signal quality, the other for signal strength.

The current converter boxes aren't made as well. The original CECBs had to meet strict specs to qualify for the coupon program.

The apex,DT502 yes they work very well I have 4,of them
I figured for what I paid for them was a good price
IT'S just like the channel master digital box 7001
That I have 2of if you are going too look for the box!
I suggest the channel master digital box is just a little bit better than the DT502.
And at least you be able too find the channel master,New not used.And if you
Buy used be careful becuse a lot of them do not work.I have been there done that.
Good luck.

Is thicker cable always better?

No, but it depends on the circumstances. Kind of like asking if a larger diameter garden hose is "always better".
