NVIS wire antenna for Emergency radio

[@KingJesusSavesSinners]

Nice video. If the station who was not hearing you well is within about 30 miles he may be too far away for groundwave and too close to copy you NVIS. The other thing is that if he is NOT operating on an antenna that works well on NVIS he may not hear you either. NVIS works best is both station are using antennas propagate nearly 90 degrees straight up. If a station is on a vertical he won't likely hear NVIS signals. If one station has ther horizontal antenna more than a quarterwave above the ground it is not optimized for NVIS. Keep working it!

I mitigate this with a crossed dipole (AS2259/Gr military style ant), seems there was no full nvis saturation which means at that specific time and area, that specific frequency was not the best, might they could of gone to a lower frequency perhaps they would have signal saturation, though yes indeed the optimum would be both stations to have the same config. A good explanation of such a matter is in the USMC field ant manual. Unlike the amateur community the military mentality is superior in targeted comms and utilize better ant to fit the specific need of the specified time..... I hope that I'm being somewhat understandable 😊 73s

Indeed, however the military goes in ebbs and flows regarding HF. When I went to Desert Storm (1990-91) in the Army I was a Chaplain's Assistant but we operated Army MARS for phone patches and message traffic back to Germany. None of the commo units brought HF with them. They were all dependent on SAT comms and it was inconsistant at best. On HF MARS we were consistently running phone patches and message traffic back to Germany. My brigade commander asked me to get him comms to the Petagon, which I did easily using a V-Beam strung up with cammo poles. None of the commo people had a clue about HF and the Division Commo Officer tried to shut us down. Fortunately he was over ruled.

Hey thanks Kj4lg! We tried again the next night and it worked great. I oriented my wires broadside to the station 20mi North of me and he got me 5x7 right up to sunset when we had to shutdown for debrief (ARES). i also canted it slighlty North on the west end, since we had another staion 15mi due west, both went well. In fact i even caught a fella in Ohio (486mi from DBQ) while i was tuning up. Great day in all. And i definitely think you're right about the frequency, it seems quite sensitive to movements up and down the band, at least with my meager 20w radio.

Been planning to make a ham & gmrs kit, in a case, like yours.

Good move!

Hey! First time I've seen your channel on my feed. I'm 80m east of you. I use NVIS with JS8Call and Winlink usually, let me know if you wanna do some testing sometime.

[@kobblekraftka0kao29]

Hey awesome!! We should be testing again April 13, around 9-11am on 40m again. Would be awesome if you could dive-in and introduce yourself. Some of the other stations involved will be WA0P, W9UPK and WA2PUX pipe-in if you hear our signals.

I run end fed half wave 40m NVIS. 9:1 unun. 66 feet antenna side, 17 feet ground side. I've reached 3000 miles on 20m, often 1000 on 40m. About 6 feet up.

@@tangobayus wow thats impressive! I'd love to hear more. You got any videos on this?
