Hello, I am a relatively new HAM for nearly one one year here in VK-Land (Melbourne, Australia) and I have a question regarding the advantages and...
For the pictured test case at 14.1MHz, does changing coax length L effect SWR seen by the rig? Yes or No? [ATTACH]
I bought an MFJ 1786 loop antenna some years ago, it arrived with shipping damage having been dropped and the variable capacitor was really...
I have three transmitting antennas. This question pertains to the one I use on 30 meters. It's a shortened, loaded dipole: two monopole whips with...
My R8 is only a couple of years old. A few days ago I noticed that my swr on 30m was extremely high. Band above and below the 30m band were good...
Hello All, Got a question for all the Icom 7300 or LDG IT-100 owners out there. I just recently got the Icom 7300 added to my radio shack. I was...
I have a TH3MK4 with minimum SWR of 1.2 to 1 at 21.380 kHz rising to 3 to 1 at the bottom of the band. (Measured using Rig Expert AA 35 Zoom) I...
Fairly new ham here. I just built my second antenna. It's a 2 m copper J-pole patterned after the one from KX4O with a mast decoupling stub. My...
I have just bought a Yaesu FT-991A to replace an FT-450AT. On the FT-450AT, I programmed the CS button to transmit a low power carrier for...
Not really sure if i can use a 2 Meter workman vhf swr meter on 40M band any input is welcome. ( even Critical Responses are welcome.
I installed a 40m dipole today and I'm having some issues with SWR. It seems it's flat on the very, very bottom of the 40m band and begins rising...
I just finished making a wire dipole with polystealth. The feedpoint hangs from a carp pole about 18 feet up. No balun. Intended for portable QRP...
Standing wave ratio is an important aspect for any ham radio station. If the SWR is too high then it can either damage the output stage of the...
I'm trying to figure out a weird variable-SWR problem with my HF station. I'm seeing the SWR vary with transmit power, and on the same antenna on...
I have a question about what my power readings SHOULD be on my Daiwa SWR & Power Meter. The signal flow is FT-450D ->> Daiwa CN-901 ->> LDG...
Hi all, I have a 200 foot run of Heliax LDF4 which runs up a pole 78 feet in the air in the trees and the N-Male connector plugs into a N-F to...
[ATTACH] Foundations of Amateur Radio SWR assumptions In the past I've talked about the Standing Wave Ratio, the SWR, and how it describes some...
My daughter bought a brand new home in a restrictive HOA development. I came for a visit and put a 40 / 75 meter dipole on top of her 6' high...
Hello, I have a 75 meter 1/2 wave wire dipole that I intend to put up in an inverted V configuration. As this is sold as a mono-band antenna I'm...
SCENARIO I have a new amp in the house and a manual antenna tuner soon to arrive. The amp is an Acom 1500, manual tune, and the ant tuner is a...
