Re: Topband: FW: Hi-Z Around Trees

My 8 element HI-Z array array is definitely in woods with a couple trees unfortunately located within 4 or so feet of the elements. How this performs with 160 DX, I'll know better after a few contests and the band opens up a bit. One thing for sure, I'm finding this system very sensitive

Re: Topband: FW: Hi-Z Around Trees

I don't have a HI-Z, but I do have many antennas in the trees here. (and have in the past at other locations too) Recently, I have installed all wire & rope 4-squares on 40 & 80 and a 2-el on 160m, all in and in some cases attached to or gently touching, (gasp!)(wait for it.) dunh dunh

Re: Topband: FW: Hi-Z Around Trees

I have a Hi-Z 4 element array that is wedged into the only available space I could figure out. It breaks lots of rules: 1. Two of the elements are less than 60 feet away from the transmitting vertical (a loaded tower). One of them is about 40 feet away. 2. One of the elements is essentially in

Re: Topband: FW: Hi-Z Around Trees

Lee, Thanks for the guidance. I plan to use 20-foot fiberglass tube with a wire down the center for Hi-Z array elements. Would you expect sensitivity to nearby trees to be about the same for these wire elements versus aluminum tube elements. 73, Paul K5ESW > > > Greetings Top-Banders,

Same reply. At our contest station, we have a 300M beverage just running through the woods and tree branches in Northern Ontario No scientific testing, but it just worked. Mike va3mw On Mon, Nov 14, 2016 at 7:49 AM, Paul Mclaren wrote: > On a similar note can I ask about

Re: Topband: FW: Hi-Z Around Trees

On a similar note can I ask about beverages touching leaves and other vegetagian. Will this result in poor performance and if so is it significant? Regards Paul MM0ZBH On 14 November 2016 at 12:41, Michael Walker wrote: > For my 80CW and 160 verticals, I have wires

Re: Topband: FW: Hi-Z Around Trees

For my 80CW and 160 verticals, I have wires suspended through 90 ft tall evergreens. I have been doing that for years and I put them in place using a drone (long before everyone was doing it). I have radials underneath. In fact, they are on a common feedpoint. Based on my 160M or 80M WSPR /

Greetings Top-Banders, I have been away for a couple days, sorry for the late comments. The fact is, for me there is no definitive answer to the effect of trees on the Hi-Z arrays. I have made tests measuring phase shifts and amplitude changes with a variety of objects around these
