Greg Lane N4KGL NVIS Information
From N4KGL: "I use a low dipole on 40 meters. I call it my NVIS dipole. However, I find NVIS hit or miss on 40 meters during this part of the solar cycle.. foF2 is the critical frequency for the F2 layer. See the link to the foF2 plot from nearby Eglin, Florida. You will see foF2 is below 7 MHz most of the time. foF2 below 7 MHz prevents 40-meter close-in NVIS like distances of 100 miles. However, the antenna is useful for longer distances. One time I was making a close-in contact with friends on the CW portion of 40 meters, I QSYed to 40 SSB and could not hear them at all. After looking at the Eglin plot, I believe at the time the foF2 was between the CW part of the band and the SSB part."
"I like the flat dipole since the other folks in the park can walk under it. I can adjust it for any band 40 through 10 I used it on 60 meters with a tuner and had success making contacts."

About Field Radio
A little about me, I am John Jacobs, I reside in Utah with my loving wife and three totally awesome kids. I am a third generation amateur radio operator, and have the call sign W7DBO of my grandfather. I am an avid outdoor enthusiast, technologist, and content producer. So! put all three together and there you have the Field Radio Podcast and YouTube Channel!
The Beguinnings - After becoming a fan of the Fo Time Podcast, then Ham Radio 360 Podcast, around the time I started a small company to help fund the hobby. I made comm and battery boxes for customers with CommsToGo.com, I became a site sponsor of the now renamed podcast Ham Radio 360 in 2016. Then, after meeting Cale K4CDN at Dayton in 2017, I pitched the idea of a podcast about emergency communications and operating in the field. He supported the idea and brought me onboard in July of 2017 into the HR360 family and The Field Radio Podcast was born! Since I a more of a media person, I also created the YouTube channel to be more of a supplement to the show. In my first six months I created content on YouTube to demonstrate items from the podcast but in end of 2017 the writing was on the wall that I enjoy video production more than audio production. So in 2018 the Field Radio project is going to pivot towards video productions.
My Goal - May goal is to give back to the amateur radio hobby through creating an educational and entertaining content that will help you learn and enjoy this hobby! In the end if you are a bit less confused about something, and more excited to get on the air in the field then we have me our goals. I only hope that a part of your journey success comes from what I give you.
