Re: [Repeater-Builder] Duplexer tuning with Return Loss Bridge
Gary, A return loss bridge (RLB) is an extremely useful tool for tuning the pass function of a BpBr duplexer. That's because the bandpass response of each cavity in a BpBr duplexer is very subtle- nothing like the peak you will see in a bandpass-only cavity. Even when three BpBr cavities are in series, the bandpass response is rather wide. An RLB allows any good spectrum analyzer to emulate the reflection capability of a vector network analyzer to a sufficient degree that bandpass tuning can be much more precise. Instead of viewing the transmission bump, you can view the reflection notch- which is very sharp. With such a clear indication of the bandpass tuning, the cavity can be tuned within a few kHz of the exact pass frequency. It is essential that all interconnecting cables and connector cables be of very high quality, and the spectrum analyzer's reference oscillator be on frequency. It takes some practice to use an RLB correctly, but it can allow you to tune a duplexer with remarkable precision. 73, Eric Lemmon WB6FLY Quoting [EMAIL PROTECTED]: Gentlemen, Will be starting a new science project setting up Wacom 641 on 2 meters.

[Repeater-Builder] Re: Duplexer tuning with Return Loss Bridge
A good discussion on testing using a return loss bridge should be found wherever the old Hewlett Packard App. Notes are on the web. A return loss bridge in its simplest application is a dual directional coupler with detectors (or power meters) on the coupled ports. The forward port samples the forward power on the line and the reflected port the reflected power coming back from the load being looked at. If you have power meters on both ports, the difference in these power levels is the return loss of the device under test. You can relate return loss to VSWR, of course. If detectors are on the ports, the detector on the reflected port will have almost equal voltage as the forward detector (for a terrible VSWR) and progressively less voltage as the load VSWR gets better (toward 50 ohms).

Mr Swan was a very big VHF weak signal fan... his designs and patents were used by KLM for their early antennas.

How do you interface an antenna to your repeater? There should be an antenna port on your repeater or duplexer t which you connect the antenna.

The 8VSB modulation used by DTV is prone to multipath interference. This is easily seen with a spectrum analyzer when turning an antenna...multipath will show up as a notch (or multiple notches) in what is supposed to be a flat noise-like energy spectrum form the DTV transmitter. Depending on where the notch is in the spectrum and its depth, the digital decoder and loose lock on the signal with the result being the dreaded blue TV screen. Thus, the best DTV performance is from antennas that are more directional which reject any off-axis multipath signals better. Multipath is why indoor antenna reception of DTV is so touchy. However, the later generations of tuner chipsets are getting much better at multipath compensation. Hap Griffin VP-Engineering SCETV Yahoo! Groups Links Yahoo!

But isn't that relative to your distance (or path) from the station you want to receive? The lower gain antennas would work just fine if the signal is strong enough. What you said is effectively (in FM terms): Simplex antennas need higher gain to make up for the weaker signals over repeaters. So why aren't there repeater antennas and simplex antennas?

Re: [Repeater-Builder] color tv antennas
Skipp, Usually I would not argue with you, but.. So your point is that the BW antennas only cover segments of each channel while the color antennas cover the entire 6 MHz segment? IOW, the BW are resonant every 6 MHz, but not continuous? Or...

It depends on whether you have an HDTV-ready repeater If not, youll also need to purchase an HDTV set-top box and interface that into the repeater.

This makes sense. I am the Chief Engineer of an FM station that recently converted to IBOC (thus having BOTH analog digital). We use the SAME antenna for both our analog digital transmissions notice that the coverage of analog compared to digital is very similar. In FM IBOC, the digital signal is 20 DB below the analog (or 1% of the analog). -- Original Message -- Received: Wed, 21 Dec 2005 03:41:09 PM CST From: Hap Griffin [EMAIL PROTECTED] Actually, it requires considerably less signal than analog TV (color or BW).

Re: [Repeater-Builder] Re: Duplexer tuning with Return Loss Bridge
Great idea (I hope) using a dual RF directional coupler as a Return Loss Bridge. We have a Bird dual coupler. Just hook up two Bird 43 slugs and meters and wham bam, tune away on low power of course. Or maybe some people have a dual needle wattmeter which would work well also? Cool beans. Gary K2UQ YAHOO! GROUPS LINKS Visit your group "Repeater-Builder" on the web.
