What is a good commercially available antenna for 6 meters. I have an
RT-70A/GRC that I'm getting ready to power up in a couple of weeks. Would
my discone suffice?

That might depend on what you want to do on 6. Local repeaters? Meteor
Scatter? SSB DX? I use a Cushcraft vertical (R6??), but I don't operate
a whole lot on 6. I have done some Meteor Scatter with it, some SSB, and
some local repeaters. Post what your goals are for 6, and no doubt
you'll get a big response!!

I'm limited to FM simplex since the RT70 only outputs FM and has no
offset that I'm aware of.

Dave,

If the discone is rated for 6 meters, go for it. I have talked to people on
6 who were using discones, even though I am horizontally polarized. I would
not spend any money on a 6m FM simplex radio.

Might try giving us operating parameters.

Are u going to operate repeaters only or skip or both?
For repeaters and mobiles, you'll want vertical polarization. (Cross
polarization can be 12dB or more)
For skip, either vertical or horizontal will do.


Can u operate SSB as well as FM - not familiar with the RT-70A ?

A discone has been described as a dummy load in the sky, wide band but no
gain.
A vertical 1/4 wave, 1/2 wave, or 5/8 wave will do better. Yagi better
still.

Can you get a yagi up 20+ feet with a rotor?

I can't put up a Yagi, so I use a Cushcraft AR-6 Ringo, 1/2 wave vertical
Your results may vary.

Have worked 48 states and 6 DX stations with it using 100 Watts. Brag brag

Have to agree with TAM- but dont expect too much- as a Discone antenna
is a no - gain, ultra wide bandwidth antenna (great for a scanner,
listening to several bands at once, but for signal strength- forget it)!

When six is open, however, all bets are off! Remember many in the '60's
running Heathkit "Sixers" working dx (1/2-1 watt output, and super-regen
reciever)! Tho, would be more effecient with a good yagi, and S.S.B.,
you might be suprised with the results. and remember: 6 meters also
tends to open during the winter solstus , as well as in the
spring/summer times! Good Luck- Jim NN7K

There is a lot of truth in what you say.

_______________________

That is an incorrect description, though. A discone has zero loss, NOT zero
gain. It has ~ unity gain with respect to a 1/2-wave dipole, i.e. ~ 2.15
dBi gain. OTOH a perfect dummy load has infinite loss. Big difference.

hi james,

Save your money, you can build this one for under $ 10,
even less if you have some 1/2 " pvc and #12 thhn wire
in the shop !

Moxon for 6m, use it vertical for FM/Repeaters
or horizontal for ssb and cw.

Smaller then a 2 element yagi but almost the same gain !
