How about a Waller flag? Better than a Beverage, since you can rotate it! Search for *Waller* or *Waller flag* in the Topband archives. Lots of information there, with a link to the N4IS page about them. 73, Mike www.w0btu.com On Sat, Dec 22, 2018, 4:20 PM Wes Stewart wrote: > I just drove

Hello Wes,     I tried 160 back in the early 70's when my brother was active from CO and we skedded on weekends. I used a long wire about 650 ft long for both TX and RX.  Working Europe was special with that setup.  I had a 75A4 RX and a t-368 RF deck with 1000 volts on the 4-400 to net me 80

I would echo the comments about running an RG-6 feedline across a radial field. I picked up huge amounts of common mode noise that got into everything. (even other beverage wires!) I had to move the feedline to cure it.  Ferrites were not effective by simply decoupling each end of the

I just drove down to the local convenience store and bought some Powerball tickets.  If I win, there's a nice 80 acre parcel across the street from me that I would buy.  Until then, I'm stuck on a 1.7 acre plot with no room for beverages. Wes  N7WS On 12/22/2018 1:20 PM, Mike Waters wrote:

Precisely, Peter! There was no DC path to ground on my inverted-L, because the tuner at the base was just two or three capacitors. A spark gap across the resistor will also discharge surge voltages from nearby lightning strikes. The tips of my homebrew shunt spark gap melted more than once from

A drain resistor would be advisable if there is no DC return path to earth... if there is no inductor or resistance between the antenna and earth it can develop wind or snow induced static voltage buildup, which can lead to discharges that will cause noise in the receiver. Static voltages can also
