Times microwave LMR 400

[iMONITOR]

What is back-of-set antenna? I haven't heard that before.

It's the telescoping whip antenna with a swivel hinge that is normally is supplied with a desktop scanner when you buy it.

That is also why I created this post looking for a reputable website that offers LMR 400 by Times Microwave or similar quality with the connections and length that I'm looking for.

...and that would be AntennaFarm.

Amazon & the bay are not it.

That's where I got my 400 and 240 with all the correct ends wrapped.

for grins i'd try an sds100, or find someone that has one. there is a guy in austin that is having the same issue. sometimes more antenna isn't the best route, with that yagi, i'd turn on the attenuator and try pointing it at some different sites. most of the intellirepeater sites in austin went to full simulcast sites, so now there are even more antennas all transmitting on the same control channel. when you look at the signal strength, it's all over the place. so even with a good antenna and good coax and in theory what looks to be good enough receive signal you could be seeing what they call simulcast distortion and that 436 just isn't going to cut it, assuming you're trying to monitor a simulcast system. just trying to think outside the box

I must have had a brain fart moment and overlooked where times microwave website offers crimped connections on their coax which I did think was odd. unless I have to call or email for a custom order.

Unfortunately that sounds exactly like what I'm going through. When the scanner is scanning the sites the signal is constantly bouncing up and down and like you said you would think you would have plenty of signal but no data comes through. I get lucky throughout the day and it will work fine for awhile with the transmission cutting out here and there. When I bought this scanner 3 years ago I was monitoring an NXDN site and was close enough to the tower where I only needed to use my diamond SRH77CA antenna. But then I moved to a different county which of course its my luck that this county is fully encrypted so I'm attempting to monitor the next county over which is the busiest county around. I was aware that the 436 didn't handle simulcast well but at the time I wasn't worried about it because I wasn't monitoring a simulcast site. So I'll have to deal with the situation I'm in and try to do what I can to make the best of it until I can some day get an sds100. However when I travel to the county that I monitor from home I have no issues at all receiving transmissions. It doesn't skip channels or anything it works perfectly fine.

Here is the county I attempt to monitor.
