Frequency has been adjusted to 13.566.9 +- to remain inside the band and part 15 complaint.

I hear you the location,location location! I set mine up in October using a inverted v at like 15feet. It was  not until a month ago I set beacon up on A halfwave endfed with matching transformer in a vertical position. On January 9th beacon was finally heard about 800 or so miles away. Interesting how location and propagation works at such low power levels. I wonder about beacons I hear all the time and power being used. Im certain now that they have really good locations that allow them to be heard often. Thankful I got two nice really tall trees or else my beacon would no way get out mounted low to ground.

Thanks for imputvand ideas. I was concerned if I needed to go lower then 4.6 mw power using end fed halfwave cut for 20 meter band losses to typical dipole or vertical being 2mw or 4 for dipole . Power sitting at about 4mw. I threw the antenna up hanging high from tree branch in vertical position.The feed point is about 15 feet off ground. The center of the wire is about 30-40 feet high.  I got swr to 1.19 and 42 ohms per the vna.  Would have gone more simple but this was easier way in my situation to get antenna up as high as I could. It would be near impossible for me to get a horizontal dipole Desired 30 or so above ground. Quarter wave I could try out. Lots of dips hills and valleys where Im at. Trying to aim high for antenna. John over at LWCA heard my beacon in SE Kansas about a week ago. I was impressed.

I suppose what i would be asking is if you take a half wave dipole feed it at any point and match 50ohms. and lets say position it in a vertical, sloping, or horizontal config would you end up with about the same field strength? This is assuming no radials or grounds.

The center fed one being horizontal or vertical.

Good conversation. I was wondering if the field strength of a 20m half wave end fed antenna with a 50ohm match transformer in a vertical position would be comparable to a 20m half wave dipole center fed and 50ohm match?

The beacon abby is currently running at 13.567.16~+~- beacon is outside. Any signal reports would be appreciated. Frequency may change soon as i have been having trouble with this beacon and already have a replacement one that needs built. Will update if or when change is made.

Thanks

I have  beacon Abby running 24 hours mostly. 13562-64 range. Beacon is in Western Pennsylvania. Any reports would be appriciated. Antenna halfwave inverted V about 22feet off ground at feed point. Thinking about maybe switching to a vertical for lower angle of radiation.

Heard both flight 93 memorial and Hudson County NJ stations. Both are about equal weakness. Fading in and out only a few words at at time audible via Toyota radio.  Hudson County was heard in Pittsburgh, PA. Flight 93 just about 5 miles north of city and at home.

22 Meter Band Beacons / New beacon KC3GFZ 13.562-3
« on: June 02, 2019, 2207 UTC »
Black Cat Systems 22m beacon with halfwave dipole at about 2mw. Running of 9v battery. Keying KC3GFZ in FN00 Pennsylvania. Will have it running next few days randomly while I do testing and locate a more suitable mounting/permanent placement. Any reception reports are welcome.

Thank you
