160 meters RX antenna for K3 advice
 
|
I am needing advice from any with a K3 for 160 receive antennas.
I just don't have room for Beverages, but I do have some backyard area. The average noise floor here is about S7 ok my Inverted L. Of course there are times it is much higher, but that is the norm. I am wondering if a small loop, EWE, flag etc is what you guys would recommend. I am looking for anyone with a relatively small space that could give advice. What would you do or have you done? Trying to get my 160 DXCC, and I'm half way there on 160.

Hi Joe,
The best RX antenna I have used is the SALA from Array Solutions. I've used beverages, flags, pennants and the DX Engineering Active RX 4 square. I have the 20' SALA version, but I'll bet the 12' is nearly as good and takes up less space. 73, Ken, K6LA / VY2TT ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Look at the K9AY receive antenna. Only needs a 30 square and 25 ft height.

I used the FAR Circuits K9AY circuit and made my own K9AY loop system. I have a City Lot and while it was not earth shattering in performance there were a few stations that I could hear with it that I could not on my inv Ell. With that setup I was able to get DXCC on 160 with 100 watts.
I would say that at least 5 were not going to happen without it. It was relatively inexpensive and easy to put up. 73 and GL Barry NF1O ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Hi Joe,
an easy and cheap starting point (weekend project) is the W2PM Mini-Diamond loop connected thru W7IUV preamplifier and KD9SV front-end saver to Ext.RX ant port of your K3. It is just 1.5m square wire loop with loading resistor and feedline transformer so it will fit anywhere even on balcony or inside of house attic. ( but I recommend to place it as far from house noise as possible) There is several other more powerful RX antennas like K9AY etc. but this W2PM loop is cheap and easy to try. Let me know if you want to send more instructions and help. The best but more complicate solution which need more space and effort in building is definitely 3-el. Hi-Z verticals array. It will fit to 15x15x15m triangle lot and it will be hard to beat I guess. GL 73 - Petr, OK1RP http://160mband.blogspot.com

Regarding the front end saver: Is the receiver in the K3 & K3S always
connected to the RX antenna? Another very good small top band RX antenna is a pennant. It is not ground dependent like some and it is inexpensive to build. K6SE(sk) wrote an excellent article on this antenna.

This is interesting and may be something to "get my feet wet"

John,
The K3 receiver is switched to external RX antenna port (RX ANT IN on rear panel) when you will select it by RX ANT button on the front panel. In that case your K3 is transmitting to one of the main ANT1 or ANT2 ports and it receiving from RX ANT IN port. ( we are talking about the main RX) 73 - Petr, OK1RP

Regardless of which RX antenna you chose make sure to detune your transmit
antenna when receiving. This is especially important on a small lot where adequate separation is not possible. 73 Jim ab3cv On Monday, February 8, 2016, Joe Moffatt <[hidden email]> wrote: > I am needing advice from any with a K3 for 160 receive antennas. > > I just don't have room for Beverages, but I do have some backyard area. > The average noise floor here is about S7 ok my Inverted L. > > Of course there are times it is much higher, but that is the norm. > > I am wondering if a small loop, EWE, flag etc is what you guys would > recommend. > > I am looking for anyone with a relatively small space that could give > advice. > > What would you do or have you done? > Trying to get my 160 DXCC, and I'm half way there on 160. > > Joe > AB5OR > > > > > > > Sent via the Samsung Galaxy Note® 4, an AT&T 4G LTE smartphone > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] <javascript:;> > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to [hidden email] <javascript:;> Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

In suburbia Houston, I was fortunate to have some nice very tall pine trees in which I had an inverted L with one elevated radial (up 20') bent to fit the 60' x 90' lot. It was fed through a ferrite bead balun. Power output was 600 watts. The rx antenna was a K9AY and one side of the rx antenna was about 6' from the radial! UGH! I 1) used rx protection; 2) decoupled the tx antenna by a relay in the coax at the 1/4 wavelength point; 3) used ferrite bead chokes on the feed line of the rx antenna, at the antenna and at the rig.
The K9AY loop has a broad rx pattern so when I set it up, it was orientated for the noise source to be in the null. I tried a magnetic type loop and it seemed to work ok but the "AY" loop was better BUT I could play with diversity reception and occasionally that made the difference between hearing and making a Q. My ON4UN low band handbook is highly dog-eared and I did manage over 150 countries at that QTH (now I am in the country).
