For 160 meters, The 4 square works very well with great F/B. ?My 8 circle works well but depending on the arrival angle of the signals the F/B varies. ?I do not think the 8 circle has ever has 30+ DB of F/B. ?I am using a ~3 foot 5/8" ground rod (8 foot rod cut into three pieces) for each antenna. ?My array is out all by itself away from any metal objects on a small hill. Lee's comment about it should have a 30+ DB F/B is interesting. ?If grounding is the key I will go out tomorrow and add more ground rods/radials and give it a try to see if it will indeed improve F/B. ?Comments? My 8 circle works not bad on 80 meters either, directional too. When I test my 8 circle/4 square and other receive antennas for F/B I try to do this during the middle of the day using ground wave from an AM broadcast station 100 miles away or so. ?This was suggested by Jose N4IS when testing the Waller Flag I built. ?When using an application called Polar plot and testing the WF I can easily see the pattern of the WF. ?This might be a trick that can be used to check F/B on other receive antennas.? I have attached a plot of the 8 circle when using Polar Plot. ?Once I started Polar Plot I switched the 8 circle through its range. ?You can read the F/B from an AM station some 80 miles away.

I have a 3 element yagi for 80M on a 130 foot tower located on a hilltop with major drop off all around. I was impressed that the HI-Z RX was on par with the yagi! The 160 RX is excellent and has prompted me to improve my TX antenna which is happening right now. Hopefully that will help me work what I am hearing and can't work. What I find interesting is the RX on the higher bands using the 4-8 Pro. My HF antennas are at 100 feet on a different tower than the 80 and also has extreme drop off in all directions. There are many times the HI-Z has improved my RX on those bands. My feelings on this the HI-Z is hearing the higher incoming angle signals better then the yagi's low angle lobe. In any case I find myself using it to my advantage even as high as 17M. Thanks to HI-Z and their fine product! Rich K7ZV > My HI-Z 4-8 PRO wrks great on both 80 & 160 with good F/B ratio.

Message-ID: Good evening all. Just recently I added a 160m low dipole for RX to the property. I put an RCS-4 remote antenna switch outside to switch between the HI-Z and the dipole. The first thing that I noticed was that when I turned the remote switch on it would blow the fuse in the switch. It ended up being the 75ohm to 50ohm feedline impedance matching box. When I removed that from the feedline the fuses no longer blew. Now I have a very bad noise which goes across the entire band. I have a P3 with my Elecraft K3. The pitch changes when I change direction with the shack direction control. The system seems to have lost some gain, has increased noise, and kept the directional characteristics that I had before. I verified the voltages at the elements = 4.9vdc, voltage at the controller =13.9dc, I have 13.9vdc going to the preamp, and all feedlines are tight. My gut tells me the preamp has an issue.

It seems so quick for us here that the holidays and DX season has arrived. We have been very busy here supplying inventory for our new alliance with DX Engineering. We aim to make this transition as easy for customers as possible. We do still maintain contact with any customers desiring information or service. Feel free to contact us. One of our new ideas just got installed for the first time this week. It is not without a couple engineering problems but first looks are pretty encouraging. So there may be a new product in the new year. We wish all happy holidays Lee K7TJR Dick KO7N Travis _______________________________________________ Hi-zreceivingarraydiscussions mailing list Hi-zreceivingarraydiscussions at hizantennas.com http://mail.hizantennas.com/mailman/listinfo/hi-zreceivingarraydiscussions_h izantennas.com From k7tjr at msn.com Sun Dec 22 14:35:19 2013 From: k7tjr at msn.com (Lee K7TJR) Date: Sun, 22 Dec 2013 11:35:19 -0800 Subject: [Hi-zreceivingarraydiscussions] Preamp placement In-Reply-To: References: Message-ID: You can leave it there Randy. There is not enough loss in your feed line to worry about. Installations with very long feedlines may encounter a slightly higher noise figure especially with the older style Hi-Z amps.

My array is aprox. 400' from the shack. The preamp was out at the array. I now have it in the shack on the array side of the feedline going into the 75/50 ohm transformer. Can I leave it there or should I put it back out at the array? Thanks. -- Randy Lake N1KWF 73 Gunn Rd.
