I saw a Laird TE Connectivity Y4503 Yagi type antenna and thought it might help me with some signal strength issues I'm having since I am unable to use an outdoor antenna. Currently I use a discone in the attic but it's wide in range. I am more interested in all of the trunked systems in my area within the 450-470 MHz range. Would this directional yagi be worth trying and would I expect to be impressed with the change?

A high gain Yagi in the same location as your discone should work much better within its frequency range. There are lots of good but cheap used UHF Yagis on ebay. I would not bother with a 3 element, get at least a 7 element 10dBd job.
If you like diy, Google how to make a moxon antenna tuned for the range in question. I made one and from indoors it does great. Very small in size
I'm probably just tired but I cannot find anything on ebay that is at least 7 elements that is not 800 Mhz tuned. Looks like there are a couple of 6 elements that claim 10dB. Yagis are completely new to me.
I'll check that out. Thank you!
@M105 posted a while back for 770. Just set your desired center freq.
772 Mhz Moxon antenna project.
I was introduced to the Moxon antenna at an amateur radio club recently. Since I had been looking around for an easy to build directional antenna to monitor the local 770 MHz P25 system I decided to run the numbers for 772Mhz and see how big the antenna would be. It turned out to be small...
I have a 5 element yagi in that frequency range and it picks up towers in the next town from in the house that my discone cannot. And my discone is on the roof.

Would be my choice
