Antenna Ideas..

Hi All,

Here’s the project I’m looking to undertake and I’m wondering if anyone has any particular suggestions about what might work best in this area? I’m looking to put up an antenna(s) for 160-20 meter use. I already have a 10 meter dipole, which also seems to work ok on 6 meters, but am willing to ditch that if someone has an idea that will go 160-6. I really don’t have a lot of room for a ground radial system; 30 feet in any direction is probably about the max. My QTH is at the top of a hill so it is a good location. Budget is also a consideration. What I’d really like and what I can afford are in separate zip codes. I’m sure this is fairly common!

My transceiver is a Yaesu FT-847 with 100 watts of output and I’ve got the companion FC-20 tuner. I currently don’t have any additional amplifiers. I’d like to see how far the 100 watts can take things by getting clever with antennas rather than just running up my electric bill with an amp  ;–]

I’ve got some ideas of my own, but want don’t want to predispose anyone to making certain suggestions. Any and all input is greatly appreciated!

5/1/2013 – Thank you to all who have given feedback so far. At this point I’m leaning towards a G5RV. Getting it high in the sky is going to be fun ;–]

5/22/13 – An update… I did go with the G5RV and using a one pound weight and some light rope was able to get it about 30 feet in the air. Worked a station from CT (K2GAV) on 40 Meters about 5 minutes after hooking everything up and turning the rig on. Still have some work to do to make the install more ‘permanent’, but I wanted to thank those who took the time to send me their feedback and ideas. This is still a ‘work in progress’ so if anyone has G5RV’s and wants to share any quirks, etc I’m sure everyone would be interested in hearing; I know I am!

  • Hi Andy!

    Congrats on the new call — your initials, I take it?

    As to antennas, while it’s convenient to have one for everything, the laws of physics make for better results with several antennas. Most hams end up with more than one.

    If you can only have one, there are several good choices, as long as you can get them high enough… right above 40 feet is generally a good height to shoot for. At that height, you will get good multiband performance from a trap dipole, a properly fed Windom or a G5RV.

    I win contests with a G5RV at 45 feet up, that runs true North and South. Any of the aforementioned antennas would also provide similar success. If you wanted to go old school, you could use a “doublet” which is a half-wave on 160 meters, center-fed with open wire pair, and is resonant on every HF band from there on up (including the WARC bands). However, as it becomes longitudinally directional on the higher bands, it needs to be oriented in a useful direction, like NE-SW, or your DX band signals will only warm up a spot in the ocean otherwise.

    You’ll get lots of other advice, so thanks for generating the interest here!

    Hi Andy
    Here is a URL to a site of an interesting antenna

    Hope it is useful in your search for an antenna

    Hi Andy
    After reading your question, I see that you don’t have that much room for antennas, however, I would say that a G5RV would be a good choice, but it needs to sit high, to really “deliver”.
    I think Joe had some good results with his on 160m even….
    hope this helped in your antenna decision.
    Good Luck!
