yagi

I have a scenario where I will be needing to point a Yagi directional antenna at a tower that's part of a phase II P25 system using simulcast. That way I can hopefully help mitigate simulcast distortion from the rest of the towers. I do not live in the simulcast affected area, only outside of...

So i am new to this and completely in the dark somewhat, i am looking at antennas and i need one to pick up a specific band as good as i can, right now i'm using a discone on my roof and i have a freqs on 453.6625 that i can pull in well enough for dsdplus fastlane to tell me what it is and the...

I searched before posting and didn't find a answer specific to my question. I have tried a Diamond X50a and Comet CX-333 at 30 ft. AGL, and both work great for every repeater I need to hit as far as 40 miles with great Rx and Tx strength, except for one. The one 2 meter repeater I can't get...

Hey guys. Yesterday I installed a Yagi antenna and it all went great. I installed an inline amplifier and what a difference. I was able to pick up a UHF site I’ve been trying to get. The quality is 5x5. I do have a 10 port powered -/+ 0 dbi splitter. I want to avoid using a regular coax splitter...

Hello, I am soon getting my BCD996P2 scanner and I plan to build a Yagi antenna for 800 mhz to listen to local police, fire, etc. and point it towards one tower. On the RR database, it has all the frequencies for the towers for my county, do I need to program them all in or just the ones...

Hey all, recently I’ve been really digging into SDR and am having a lot of fun with it. That said, I’ve finally figured out trunking and am able to pick it up and decode, but the nearest system is almost all encrypted. The city closest to me that actually has anything on their trunking system is...

Hello, I am trying to create a pet tracker and was wondering if its possible to use a monopole antenna to send and receive signals to the handheld device from the pet collar, and then to track the location of the pet collar, use the yagi for directional finding. So the pet tracker would...

I'm looking for some advice from others that know better than me with antennas. Is it worth it to have 2 separate antennas for VHF/UHF and 800 Mhz? This will be for a base application and in the attic. I have an all-band mobile with a ground plane currently using as my base on a 10-foot mast...

My old setup was just 2 telescopic antennas and 2 SDRs and it wasn't great, and with that, I wasn't getting the best reception and so I wanted to listen to systems that were farther away from me and get better reception on my local systems. I started doing some research on a better antenna setup...

A mystery I need help with... Details & background: I'm a volunteer firefighter/EMT and wear a pager (receiver) on my hip tuned to a VHF frequency (150MHz). In my basement I'm getting terrible reception on that pager, so I threw up a 4 foot tall Diamond VHF omnidirectional antenna (Diamond...

Hello, I've just found the top of the rabbit hole that I was in for the last hour getting lost digging through this forum. There's allot of knowledge here and I was wondering if someone could help lead me through my signal issue I'm trying to solve. I have two signal amplifiers on...

In my area, there is a P25 system which continues to expand and has 13 towers within my county alone. The multipath from overlapping signals on the same frequency makes reception annoying and often unintelligible in mobile or portable listening. I have tried various adjustments to my Whistler...

Hey All, Not too familiar with antennas so I was wondering if you could help. Have an old Yagi TV Antenna mounted to chimney from way back when (was there when we moved in). Found the old coaxial cable today and was wondering if I can set it up for scanning? Images If it is able to be used...

I am in the process of building a homemade yagi (for 2.4GHz). Once done I would like to be able to protect it from the elements and thought I could place it inside a PVC pipe. I cannot find any definitive answers on the web regarding the effects of PVC and 2.4GHz. Would PVC have any effect on...

I live in a condo complex where no External antennas are allowed. I want to mount a Laird 9db gain yagi antenna indoors (no attic) somehow but can't figure out how to do this so it stays pointed towards the 800mhz systems I want to monitor 30-40 miles away. Any ideas? PS I am using a BCD436HP...

I'm wondering what type of cheap alternative there is to a log periodic antenna... something that's broadband, directional, high-gain, but low-cost too? It occurred to me in looking at log periodics how much they resemble regular 'ol TV antennas. I'm not so naive to think I could put a TV...

Hey everyone, I'm going to be putting up a Scantenna pretty soon and am thinking of putting up a yagi with it too and I was just wondering what type of range could be expected with a good yagi? I would like to pick up Springfield's 800 mhz system but live 70 miles from their tower. My mast is...

Hi All, I am new to the world of scanners and recently got my first one. Before this I was actually listening to online scanners but they had nothing for my country. (fyi, I am from India). Please read the brief desc first :- (correct me if i am going wrong anywhere) I have got a Uniden...

Recently acquired this old UHF Yagi, which is pretty generic looking. I'd like to maybe figure out who manufactured it, and if there was a model # for it. I haven't swept it yet, so I'm not even sure what frequency it's resonant on. Anyway, here are a few photos of it. The mounting plate on...

hello all, newby here. this looks like the place for some sound advise on scanner/receivers so here i go. my friends and i hunt with hounds and use VHF tracking collars to keep tabs on them. some use 155 Mhz and others use 217s. the matching proprietary tracking devises have receivers that...
