Before I begin, I want to thank everyone for your continued support and encouragement. Even though i got my ticket in 1977, this is a new facet...
Hi: Enjoy and/or criticize this blog post. It is a fairly comprehensive look at the propagation pattern of yesterday's SOTA/POTA of Mt Wachusett...
Shawn has a very different installation of his feedline to the StepIR Antenna. The installation is mostly about noise reduction. Shawn does a...
As I look around the Internet for information on building EFHW UnUns, I see the ratios of 49:1 and 64:1 appear quite often. I get that these are...
WSPR is a great tool to look at and measure propagation on the various ham radio bands. In this video I test my EFHW (end fed half wave) antenna...
Hi all, first time posting on these forums. I'm looking to build an end-fed half wave (EFHW) antenna as my first HF antenna -- hopefully before...
Hi everyone, I have been changing my antenna configuration a bit for use with my Yaesu FT 450 D. I use an end fed half wave HFedz antenna. It is...
I have this weird problem, I connected a new EFHW antenna, EFHW-8010-2K-Plus, to my Icom IC-7300. When measuring the SWR, the IC-7300 SWR meter...
I'm building a 49:1 EFHW for 60/30/15m in an inverted L configuration with 12ga THHN wire - about 30' vertical and 60' horizontal (40' AGL). Am...
I am a new ham, passed my Technician and General. I would like say the words of wisdom, "I am in over my head" Before I got my license I...
The NEC4.2 analysis below shows that for the installation conditions in the graphic, the input Z for a 1/2WL conductor fed 5% from an end is...
Hi.. I'm considering an 8metre roach pole as part of a Efhw antenna. The vertical element will be the 8m but then it needs to support a 12m...
Here is a little comparison between my homemade Terminated End Fed antenna and a traditional EFHW antenna. The difference in receive signal is...
Working on a 1:1 transformer and thought I would share two charts. Let me say right up front that this is not a scientific comparison. Things to...
I've been looking around for a simple theoretical picture of end feed half wave (EFHW) dipoles, but haven't found a complete picture anywhere....
Howdy, I've got a 130-foot-ish EFHW antenna, it's cut for 80, but i'm getting SWR of 3-5 across the entire band. Googling has told me I should...
I have a 80m EFHW that I'd like to use on 60m and 160m if possible. Anymore I run a vertical and do rather well with that, but not enough space...
After doing a fair amount of research I've decided to purchase a myantennas.com EFHW-8010. Now that I'm ready to make the purchase I see that they...
Answering the challenge Here is the first test setup partially answering Rege's (AI3V) challenge of placing a small transmitting source at the end...
I am creating a presentation on "End Fed Half Wave" antennas which will be one of the tech. forums at the upcoming Prescott, AZ Hamfest on May31...
