antenna

i wanted to know about some good portable antennas (bnc) that wont stress the bc125at bnc connector, preferably telescopic and having some good range? i would prefer if it was wide-band capable, i have seen posts about the rh77ca but i wanted to know if there was any other goodones. i would not...

Hello all, I hope I am posting this in the correct place. I am a technician class operator who just purchased an icom IC-7300 with my tax refund (thanks, Uncle Sam! lol) I intended to take the exam to get my general license and then use the HF bands for voice communications. However, I currently...

Good day, Got his cheap antenna: https://www.tme.eu/Document/ab28b11ed5a07f3d86b2cbf91b5e11e7/433M-ANT824.pdf Trying to use it as a way to check my measurement-taking setup and equipment. - NanoVNA calibrated at S11 port for 50 ohm - Plastic stand for the antenna with good clearance around...

can someone tell me will this amplifer let me listen to vhf and uhf frequencies by amplifying them. Channel, Cascaded Ultra-Low Noise Amplifier

Hello engineers I have a question about a log-periodic printed antenna For feeding through a coaxial cable and creating a balloon, where the shield is soldered to one side and the core to the other, Should the shield be soldered to the end of the stripline path to the board? I saw in some...

I have a Zenith Transoceanic, model A600. I recently replaced the Wave Magnet's 300 Ohm antenna lead-in wire, and noticed that the loop windings on the antenna's core are wound differently at either end. On the end where the lead-in wire is soldered to the loop, the windings are consistently...

So right now I have a Bc125AT and I am going to get an sds100 soon. I want to have an antenna on my car so I can achieve extended range. I like the “ghost” style and sharkfin style but I am open to having an actual antenna. I know that the roof of my car has the highest range so ideally I would...

Greetings all, this is my first post on the forum. new to ham radio. Currently using a handheld, yaesu ft-70R. Phoenix, AZ seems to have a fair number of fusion/wires-x repeaters so I’ve been learning about those. thinking of upgrading to more power so I’m looking at the FTM-500DR (the...

I’m just starting out listening to shortwave radio, and I have a 15’ length of 14 gauge, insulated, braided wire strung in the attic of my stucco construction home. But the roof tiles are made of 1.5” thick cement – how does this impact my reception? Should I even bother with an attic antenna...

I need to know whether the radio receivers that are highly sensitive, like having sensitivity less than 0.0224 micro volts for AM reception, encounter less fading than the others with less sensitivity? Which specification of a radio receiver is responsible for mitigating fading?

Hello everyone! General question: Is the telescopic antenna that came with the SDS200 radio have good range compared to a dipole? Backstory: My SDS200 is connected to a 50ft low-loss 50ohm cable connected to a dipole. I live in Eastern Kentucky ( Letcher County ) and range and reception is...

a few years ago i found my old Uniden Pro538w in a box in the basement, a buddy of mine had given men 2 102" whips, so i made a vertical dipole with them with the center mounted about 15ft up (where the coax connects) on my chimney... meh, i don't hear much, i just assumed CB was dead... then i...

Ok i have looked at tons of antennas and i am confused on a few different things for example a dual band and a tri band antenna if the tri band lets you cover more why would people even bother with a dual band is it because that if a antenna is programmed for a specific freqs it will pick up...

Good morning all. So I am bringing my SDS-100 up to Overgaard, AZ (Navajo County) which is extremely rural. The upgraded antenna (same size, just don't remember the manufacturer) works great to pick up the local stuff. However, things like Highway Patrol, the next city over, etc., which are...

so i built this linear loaded SWL antenna, a project i found on the swling website, which involved getting a a NooElec 9:1 balun in the middle of two 15ft pieces of romex bound at the ends in a way that it effectively makes a dipole with 45ft elements. this balun is not made for any kind of...

I am licensed but inexperienced. I bought a end-fed random wire antenna with the 9:1 balun. It held up poorly over the year. The wire is nearly torn apart, and of course I can replace that easily. But I am not sure it was ever working, and I don't know how to test the Balun to be sure. I...

I have used my small loop antenna (which has a main loop and a coupling loop that can be tuned using a variable capacitor) with an AM radio receiver to receive MW broadcasts. However, the small loop antenna which was made by me was not working properly but when I connected a ferrite rod loop...

So here is what i want to do, i have two antennas that i want to mount one is a discone and the other is a j pole and what i am trying to do is use a piece of pipe that is no bigger than 1' 3/8 in diameter and put the discone ontop of the pipe and midway's down attach the j pole i have already...

So i have been struggling to figure the answer out to this question for a while now. I bought the RTL-SDR kit and i don't know how to configure the antenna, videos on youtube have conflicting answers i see one person say use it one way and then another person in a different video says to use it...

I have a 30m EFHW resonant sloper antenna. I've completed tuning it using my RigExpert and have an excellent SWR at the antenna and the TXRX. I know that some common mode currents are present, so I have a CMC filter at the antenna and in the shack. I've attached an image showing the antenna...
