antenna

Trying to revive an Electra Bearcat III scanner (pretty neat old scanner) but the antenna that screws in down through the top has went missing. Trying to locate one to keep this little project going.

So I've been looking around for a new antenna and I've come across the EM wave brand. The antenna are bit more expensive but they seem to be built well from what i can see. The problem is a Google search shows barely any reviews. Anyone here own one? How do you like it? Also, I've noticed tram...

I'm a member of my local fire department, where we have this airboat equipped with a dual band radio. It may be hard to see in this picture, but the antenna is mounted toward the front, right in front of the cab. Transmit quality is not great on it. Since it's a fiberglass boat and that...

Hello, I’m looking for some help in upgrading my mobile antenna. Right now I have a tram 1199 through the glass antenna but I don’t get great signal and feel that I miss calls on the scanner. I listen to fire departments on the p25 system in Rhode Island and that is what I feel I don’t get good...

So our agency is going to trial Zello for public safety. Below is our configuration (simplified) if you're interested. To get to the point. I'm looking for a base antenna for a VHF Motorola PM400, the frequency is 159.6. Below are the options I'm considering, any thoughts or opinions? Laird...

Hello! I recently picked up a magnetic base antenna mount with a 16' cable at a local yard sale. It did not come with the antenna itself. I am having trouble identifying what kind of connection that this mount has. The connection has female threads that are bigger than SMA, and has no pin or...

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 just recently bought 2 Browning BR-137 Tri-Band antennas for my POV and something occurred to me; Do antennas have a MPH rating? Is there a certain speed they are rated for before they weaken & become a projectile thru someone’s windshield behind you?? I’ve tried looking everywhere and cant...

Looking for D220R Or a D. too 20 any make possible Would prefer under$50 at possible as I'm trying to replace products that I lost during the paradise fire Here in California Any help would be appreciated thank you

This is my first time posting so I will try and include as much information as possible. Recently I purchased a Uniden BCD436HP, 100ft of LMR-400, and a tram 1410 disc cone antenna. After receiving the Uniden I connected it to the antenna approximately 25 ft above ground. I updated the...

I just received the RHWA-450 -SBM Scanner Antenna from Arcadian. I'm pretty sure its helping my UHF and VHF but concerned that the BNC connection doesn't fully lock on my TRX-1. Seems there is a bump that prevents the antenna from fully locking onto the Whistler. Should that be a concern?

This morning I tried buying different scanner antennas to my apartment in CA. I just can't believe it. The message kept coming up can't deliver to your location. Has something to do I think with warranty issues. I had to order an antenna from somewhere else.

I'm surprised no one has asked this yet, so I guess I am the first. Does anyone know if scanners produce harmful radiation if you're around them a lot?

I'm not radio savy so this might be a dumb question. Can I use a 430-470Mhz UHF antenna on my UHF ht 750 that's 403-470MHz without harming it? Or should I just buy a 403-470MHz antenna?

I am building a dipole antenna. I know that the feedline needs to be approximately 1/2 wavelength in length (or factors there of) for best SWR. However, there is one item of confusion. I am making an RF choke by coiling the feedline at the base of the antenna. Do I include the length of coax in...

This is probably an obvious to most that are experienced with scanning, but will a mobile/portable antenna that is designed for a specific band ALWAYS perform better in that band than one that is designed for multiple/all bands?

What rooftop antenna models work nicely for VHF and UHF low? Any suggestions for ways to elevate the antenna signifigantly higher than my roof? Thanks

I am looking to buy a mobile antenna from scanner master for my sds100, and most of my area has VHF and low band UHF. https://www.scannermaster.com/Laird_Multi_Band_Mobile_Antenna_p/20-541858.htm and https://www.scannermaster.com/Wideband_Antenna_with_Mag_Mount_and_BNC_p/01-541326.htm It seems...

So I currently live in morris county NJ and i want to receive all frequencies coming from Newark Liberty International Airport, which is a county over from me (19 miles from me). It's frequencies should be available under essex county on the RR database. I have an sds100 programmed and...
