Which is Better Receive Antenna: Long Wire Vs Resonant Antenna (

Matt, AG4JT, has a polite disagreement; on resonant atenna you can hear better and he said that the more wires you put in the air the better you could hear. Watch to learn more.

Thanks Dave for clearing that up for me. Cal from DX Commander and Roly from NZ had a discussion about while we no longer have separate transmitters and receivers, it may be time to look at separate antennas for transmit and receive due to the noise floor slowly getting more challenging each year. Roly has a random wire loop around the perimeter of his property about a foot off the ground for just that reason. 73 from Moose Jaw Tim VE5THF

Thanks. I've often wondered about that. Now I know.

I've ALWAYS had metal. Yagi's, di-poles etc. My rotatable 20/40/80 di-pole became intermittent. So I put up a NREF via a 9:1 unun with 190 ft. of wire (#12 THHN electrical wire) that I had laying around. Apex at 50ft. east to the tree(70'), south 100' to garage and west 20 ft. to corner. 1.1:1 on 160 (which I never got before) to the worst swr on 40 at 1.7:1 back to 20mtr at 1.1:1. All without a tuner! Europe and states due west (I'm near Lake Michigan) never came in so good. Like Dave said, I might not have the gain, but I don't have to wear out a rotor. I love the omni concept, especially living here during a net. Half the contacts are east of me and half are west of me. If I can hear them, I can talk to them (with decent signal reports) 73 W9DLP

Very interesting subject, and well defined!!. Thank you Dave.

Thanks for sharing information 😊

I'm getting into smelting and have been learning the difference between cast aluminum and die cast aluminum. I was thinking about casting antenna elements with the material I get from aluminum cans and other aluminums. My question is: which would be a better material to use the pure cast aluminum, or a die cast aluminum. Understanding that Die cast is more rigid.

[@peterfitzpatrick7032]

Die-casting would have better physical strength as it is injected under pressure so it would be more dense, its would also be more homogenous and unlikely to have any impurities or porosity... But die-casting is also an expensive process with fancy machinery reserved for mass production...🤔 😎👍☘🍺

[@davidc5027]

I wished Dave would have gone into the transmission line as well, because typically with "resonant" antenna's they use coax as opposed to long wire which uses ladder/window line. So, I kind of took his explanation as though the receiver was at the base of the antenna. Was just something I was thinking about.

[@pumaspaw]

Now you got me curious too. If I remember right, ladder lines is often used with nonresonant antennas, but there are certain lengths to be avoided. I'd love to hear Dave's thoughts on how the different feed lines affect reception in both resonant and non resonant antennas.

[@davidc5027]

​@@pumaspaw I'm going to rephrase because I don't mean disrespect, and some times the way things are typed they seem that way.

[@KuehncIncorporated]

Great Question and Answer

[@michaelnoardo3315]

i bought a loop antenna that covers 10khz to 500mhz and i simple can make any wire works better than my loop, Im really impressed with the quality of this Loop Antenna

[@peterfitzpatrick7032]

Dave, I would never have thought a longwire was more directional than a resonant...🤔... I wonder , would the longwire be terminated with a resistance ... and what effect terminating vs. not terminating has on the characteristics of said antenna ?? 😎👍☘🍺

[@ronjoseph7973]

My experience is reception has less to do with antenna type but more to do with the amount of QRN and QRM operators encounter. The new SDR transceivers use DNR (digital noise reduction) to increase the signal to noise ratio. Many hams are using various web SDR apps to get the best reception, relying less on their station antennas.

[@Yosemite-George-61]

hello! I just stumbled here... I'm not a ham radio operator, just a guy with a long wave radio (and Mw FM) I dare to ask, what's a good way to improve Lw reception? I'm confused between ferrite and loop antennas (I'm a newby) . Thanks, cheers from Normandy!

[@sktechguru123]

Nice sir 🙏 Ji

[@Appsandgames2]

Hi Dave. Can you give me the best antenna sizes to polarize the 1800 frequency?

[@CharlesDonaldson-oz2dl]

I don't think anybody is worried about how well they're receiving antenna will transmit. I'm just saying, tho. But I am having a hard time searching for receive antenna or receive only antenna information because apparently no one would use them so they want us to have an antenna that will transmit as well. I was thinking it would be logical to believe that there would be antenna types and etcetera that were are better for receiving that could best be put to use on an antenna that was meant never to transmit. Everyone wants to talk about transmitting on the receiving antenna. How well it will do it.

[@maartenc6099]

I disagree with a part of your explanation. A wire of a half wave length is resonant. If you feed it at the middle you have a dipole of about 72 Ohms impedance. But you can also feed it at the end, it is still resonant, but the impedance is very high. Resonance does not mean that the impedance is low.

[@bagginshates]

Here I learn that receive performance is not related to transmit performance.

Dave you sound like a Politician ! 👍😂🤣😂
