antenna

Hello, I have a MXT275 radio and the Midland magnetic antenna mount in the center of the truck cab and an MXTA25 3db antenna and it was all working fine but I decided to reroute the cable and purchased an extension cable but when I fully plug in the cable to the radio I get nothing, when I pull...

Howdy, my first full GMRS radio- wondering about the difference between the antenna and how it affects TX and RX- when to use each thanks

***SOLD*** Here is a blast from the past! The Antenna Specialist MON-5x family of antennas were the best scanner antennas of the day. If you had low band in the area they were awesome but also performed great on VHF and UHF. This package contains the following items: 4 MON-51 wide-band...

I had a 5/8 30 inch UHF antenna mounted on my car. Its a 5.5 db gain antenna with two coils and I just noticed as I got home that the top part is missing. It must've gotten loose and detached from the top coil while I was driving. This antenna is used for recieve only, no transmiting and...

I have a Tram Model 1465 Base Ground Plane Kit that I am going to use with an NMO mount antenna for a DMR repeater at work. Repeater TX is 469.2875 an the Reaper RX is 464.2875. The kit comes with 20.5" radials. do I need to cut them down, like the Antenna, or should I leave them alone. If I...

Thanks for accepting me as a member. I have a loop antenna at the end of the garden, and my computer is in a downstairs room in the house. I'm about to order a 30M RG213 coaxial cable with BNC Male connectors on each end. What's the best way to connect into the house. Ideally I would like...

I'm new here, so please be gentle with me. I am going to be putting up some antennas at my house soon (GMRS, CB, 2m/70cm, and Scanner). The last time I put up a base antenna was roughly 48 years ago and I know things have changed! Here are some questions I have. All of these antennae are...

I have 4 SDRs that i want to use on one antenna for 800MHz trunking. How can i properly figure out how many sdr dongles i can have connected to it before signal gets too low. Im getting a Nooelec LNA that has +20 Db of gain.

Hi all, I know the Diamond RH77CA antenna is the gold standard for the BC125AT scanner but I'm looking for an antenna and a NMO magnetic mount that can be easily attached to and removed from the roof of a rental car. My frequency range of interest is 150-174 MHz and 410-470 MHz. By the way...

Hello! I've recently just invested in my first airband scanner (the Uniden UBC75XLT) for me to use when visiting my local airports and it works great and wasn't too expensive, so I'm very happy! I'm also now looking, and I'll be honest I don't know if it's even a possibility, if there is a way...

I want to mount three of these little guys on my car using a triplexer. Anyone have any idea which would be the best one to use to split the signal between the three? I could do two but would rather use three for better coverage. Looking for best recommendations to accomplish my goal. Not...

Hi guys, This kind of antenna is commonly used by brazilian truck drivers to communicate with UHF Milsat. In Brazil this satellite is known as "bolinha" and you probably already heard about it. I'm wondering if this antenna design really makes sense for satellite communication or if it was...

Hey folks. Got an A99 today and the Mrs thinks I need to paint it black to avoid Karen. Any suggestions on paint? I’ve heard that some spray paints may ruin the antenna so didn’t want to grab just any random can from Home Depot. Robert

Has any run into a issue where you have 2 feeds running on 1 raspberry pi and using 1 antenna where the audio mixes on both feeds? When I use 2 separate antennas and the audio mixing goes away.

Suppose that I'm installing an omnidirectional antenna for both transmission & reception purpose at the elevation of ≈100ft. If I want to effectively communicate with a few targets all at the elevation of ≈0ft and horizontally ≈5100ft from the antenna, what's the maximum acceptable gain for this...

I interchange antennas frequently on my sds100, and I was wondering if there are any adapters that I could put on that will take the damage and wear over time, rather than the scanner itself.

Hi All, I'm new to amateur radio and I'm trying to set up my shack and could use your help. I bought a Tram 1481 antenna and plan to mount it on the side of my covered roof back porch. The porch is 20 feet off the ground, since my house is on a hill that slopes down behind it. The supports...

Been around CB's several years but all mobile, never a "base" setup at the house and I am a novice all the way. The setup will not be using any amps and the base will be a Galaxy DX 2547 (stock as far as I know). So it seems the more I read the more I get confused. I have read over several...

Hey folks, First of all, I'm a newbie. Not knowledgeable at all. But I recently purchased a used PSR-500 off eBay and I'm pretty stoked because I've always wanted a scanner. Somehow I have, with the help of software, been able to program my scanner to receive my local emergency talk groups...
