Ideas for a home built 2meter/440 dual band base antenna
Does anybody have any good ideas for a good dual band
2 meter/440 antenna? This would be a base antenna and should be capable of handling 200 watts. Thanks Chip |

This is a real easy antenna to make and works really well too.
http://www.arrowantennas.com/j-pole.html is the link that works. 73 Richard WB8KRN "Arrow146" wrote in message ...

i would suggest going to www.ac6v.com and clicking on antenna projects
or do a google search for dual band Jpole or copper cactus good luck Ralph Blach wrote: Does anybody have any good ideas for a good dual band 2 meter/440 antenna? This would be a base antenna and should be capable of handling 200 watts. Thanks Chip |

I would be very tempted to try a discone in this case - just to say I made
one. practically no gain - but I hear they have extremely good bandwidth - and different enough to start interesting QSOs locally "Ralph Blach" wrote in message ...

I guess my question would be... WHY do you need 200 watts on 2 meters or
440mhz for that matter??

To get better coverage in and out, altitude is your best bet. Our club's repeater (actually both of these bands) is on top of a 6 story building, and others in the area are located even higher above mean ground level.

You are, of course, joking. Why wouldn't you want an antenna that
handles at least that? 200 watts is low power on VHF and up for many of us. I would expect any fixed antenna system I use on 6 or 2 to handle full legal limit, and 70cm to handle 500 watts minimum. I will admit you normally wouldn't use vertical polarization with that much power, but I still want my antenna/feed systems to handle it without a problem. tom K0TAR Paul Jordan wrote: I guess my question would be...

No, I'm not joking at all.. We use repeaters here in Alaska that are on
nice tall mountains all over the state. Check out the Arctic Amateur Radio Club repeater page sometime. Thier repeaters system has over 60,000 square miles of coverage.. I can access any of thier repeaters with a 5 watt handheld. My Icom 706 only has 10 watts on 2 meters and I've never had a problem with reception or transmission into a repeater. I guess we're just not into the long distance contacts you outsiders like to do down there in the lower 48. What's funny is, you can work satellites and space shuttles with 5 watts and a hand held Yagi... I still can't see the need for all that power on 2 meters.. I guess if I need to reach out farther, I go HF.. That's what makes this hobby so interesting though, we all have different interests. Tom Ring wrote: You are, of course, joking.

QRO is fine if you live in a thick rain forest and can't get your antenna up
over the treetops, or if you're using Morse or SSB to set a new distance record, but otherwise, otherwise. Before PL tones became SOP my main VHF/UHF problem was pulling up multiple repeaters with anything over 50 watts and even that was too much on some frequencies, so I learned to strictly limit my power output. Nowdays most repeaters have PL tones that prevent unwanted activation BUT using enough power to trigger them with the tone means I'd be interfering with QSOs on them even with the PL off. If I come up with a 100 watt signal, sans PL, but some OM close to the repeater keys it up with a HT, my RF and voice is going to QRM his. Thats why my VHF/UHF amps have gathered dust for over 10 years and my primary VHF/UHF rig is a VX-2R. 73, K3DWW "Tom Ring" wrote in message . .. 200 watts is low power on VHF and up for many of us. |
