Splitter = Combiner?

[passedpawn]

Anyone know if a splitter can also be used as a combiner/diplexer? I have joined two antennas this way, and it works, but I don't get the best reception from my UHF. I assume since it does work that there are simple passive components in there that are bidirectional (i.e., no diodes).

I know I should use a Jointenna (for CBS in Holiday). I'll probably go that way later anyway.

I tried to use a spliter as a combiner, and had the same problem.
I replaced it with a combiner that filtered and my reception improved greatly.
I used one very similiar to this.

Thanks much. I think I will try that out after Christmas.

Use the Channel Master JoinTenna. That is what it is for. I bought several online for $25.34 each from Warren Electronics in Illinois. The sales rep told me Ch 24 was the most popular. Maybe they do a big business in this area. :?:

The Jointenna is a great product but to my knowledge they don't make one for this. The Jointenna is so you can add an antenna for one channel. If you simply want to have one antenna for VHF and one for UHF, I don't think any of the Jointenna's will work.

For Tampa you have to have two Jointenna's, and 3 antenna's. One for UHF, one for channel 8-1 and one for 13-1. This would be different for analogue.

Sorry; I misread the post.

Actually, the Ch. 24 JoinTenna is exactly what I need. I have a combined VHF/UHF for Riverside. The separate UHF antenna that I mentioned above is soley for CBS (24) in Holiday.

Right now, I am using a splitter (!) to join the two antennas... curiously, it works great for 24, but I am seeing interference on other channels. I expected some interference at some channel. The jointenna should cure this.

For details of why this will sometimes work, search google for hdtvprimer merging feedlines.

Splitters are used as combiners all the time in my job. I use all sizes, up to a 16-port splitter, to combine my signals at a headed that may have up to 60 channels combined.

If you use a splitter that is rated for up to 900 or 1,000mhz, then UHF should pass through it. There will be loss; typically about 4db for a 2-way splitter, and maybe 6db for a 3-way splitter.

The reason for using a join-tenna in a two-antenna setup is to keep unwanted-frequency side-lobe signals from the ch-10 antenna combining with your main antenna signal and causing ghosts or multi-path signals.

If you install a ch-24 join-tenna now to get the CBS digital signal from Tarpon Springs, you will have to put a ch-10 one on there after the transition, since I think that they are going to assume their original frequency.

Chances are, if you are using one of the newer digital receivers that you won't have any problems with multi-path. I'm currently in the middle of installing digital converters on many of the hotels in this area, and am surprised how well the converter tuners are working. I often can get all the local digital stations from a single antenna.
