CCW Vertical Dipole
Chris, Just a quick note - the vertical dipole is working splendidly on 30m Rx (not too shabby on 160 either). I've never worked Tx on 30m before, so my project this weekend is to finally cut a dipole

Active antenna overload protection...how close can you go?
Hi All, Apples to oranges, but for comparison on the LF/MF side: I have a CCW vertical (monitoring 137) mounted about 15 meters away (12 meters off the ground) from both of my Tx vertical antennas, on

VLF/LF/MF/HF Active Vertical VLF Performance
Robert - Oh, there's plenty of noise here, and we live out "in the sticks". I usually see a pretty steady S9 on both 2200 and 630. I might add that the CCW active vertical is also great for MF NDB's (

VLF/LF/MF/HF Active Vertical VLF Performance
Hi Robert, Thank you for that report - very, very interesting stuff. I've had good success with this antenna on 2200 and 630m. On occasion I like to go up to 80m and "watch the traffic go by". Last ni

Summer LF conditions !
Even though we're about 1300' AMSL, we're also totally surrounded by heavily forested terrain (oak, sugar maples, beech, etc.) - so it's always tough going this time of year. BUT, we had our first -34

VLF/LF/HF Active Vertical !
Just another update on the 630m side (from FN32vx). Last night was the first night I monitored WSPR2 and JT9-1 with the CCW on 630. Extraordinary activity here on JT9-1 and -2, with several stations c

VLF/LF/HF Active Vertical !
Chris, from my understanding, 1W EIRP on 137 is gargantuan. Using the VK1SV calculator - the Hafler P3000 at 400W TOP is <500mW EIRP after going through the variometer. That places the voltage ~17kV.

VLF/LF/HF Active Vertical !
Just an update: Using this CCW antenna I (as WK2XAH) snagged a personal best of 3594 km 4-FSK (WSPR2) Rx from WH2XND on 137.5 kHz. Plenty of good activity on 474 also (up to about 800 km), but this wa

VLF/LF/HF Active Vertical !
23 Jun 2019 - 1802z - Greetings from the Granite State (New Hampshire) ! Installed the active vertical just in time to Rx the ARRL Field Day message from K6KPH in California (~4268 km) on 20m. Photo b
