I have used several 6 meter antennas, all with good success at low heights.

Homebrew 2 element quad, 36 inch boom, on an MFJ fiberglass pole, strapped to a 2nd story deck - worked excellent, for portable work, very light weight, just need a philips screwdriver to assemble/breakdown. I'm going to update the design for no tool assembly. Uses a 1/4 wave 75 ohm coax for matching.

I built a 4 element 6m quad that worked excellent out of questionable materials, it came down in a wind storm, but proved I could make an awesome antenna. I'm building another one this year out of better materials and using an antenna analyzer program to optimize it.

I built a 4 element 6m quad for my dad and he loves it.

I made a 6 meter moxon using 3/8 OD inch tubing. It works great and has great band width. Lightweight back up antenna if I need it. Uses a PVC boom, less than 4 feet long.

Currently I use a 4 element yagi with a t-match. I picked it up used from an old timer almost 20 years ago (found in the Ham Radio Yellow Pages!!), but don't know the brand. Works great even at a low height (25 feet)

I used a Ringo AR-6 for a bit at the old house, good for repeaters and hearing Europe.

Never used more than 100 watts - yet

6m Ringo on a mast, 20 feet above ground, no more than 20W. Works for me.

5 element Cushcraft at 60 feet.  Run up to 100 watts if needed. Try to use lower power when possible.

"his would be incomplete if the author did spill the beans too....I just built a Moxon (a U type) using 3/4 in
PVC. I won't be doing that again (droopy POS!) "

I've got a Moxon too:

http://www.n3ox.net/projects/sixmoxon

It's a "Home Depot Special," where everything but the coax, connector, and ferrite beads was available there.

It's held up surprisingly well over the last few years.

Recently, I added a five element wire beam constructed with crappie poles much like the popular HF Moxons...

http://www.n3ox.net/files/sixyagi_lg.jpg

Works pretty well, maybe 4-5dB gain over the Moxon.  It'd be 6dB at low angles if it were up a little higher.  It still works noticeably better in most directions.  

The two antennas are too close together and so they interact to the tune of a few dB loss when I point one at the other.  Eventually, I will probably take the 6m Moxon down now that I've proven the performance of the 5 element yagi.  Last season I had a hard time comparing because I was using the old Armstrong rotator on the 5 element... hard to peak up

Two 6m Antennas.

GP-15 Multi Band at 25 feet for 6m FM.

M2 6m HO loop at 30 feet using 9913.

Both at 100w.

Used the GP-15 peak of last cycle, had a blast on 6m SSB with it.

Ok! I have a homebrew squalo at 24 feet(I worked Scotland with it last week)!I ran 100 watts thru 100 ft of 20 year old rg58!

I have a 4 el Hy-Gian beam in the garage being re-habed!This will go to thirty feet on the house chiminey in a few weeks!

I am building a moxon and hope to have it up next weekend!

The 4el Hy-gain is a decent antenna. I have had it for since 1966 and worked many states using 20 watts on AM!

Here i currently have a Eagle 6el with 6m boom up about 65ft.

planning to change to a 7el YU7EF (homebrew) on a 9.5m boom.

in EI we are only allowed 100w.

Intresting to note all the homebrew antennas and the lack of yagis Huh?

hope to hear some of ye over here before the season ends

for 6M:

Assorted radios with power ranging from 1W to 200W depending on mood.  All but one HB.

Antennas 4 elements HB at 35ft, also a lawn chair
(the round tube with bends) converted to a square loop
at 18ft.

Mobile, HB QRP SSB, 100W HBamp and KU4AB square loop
mounted in the bed of the Tacoma.

For field work, Par EF6, Copper Square loop, Driver reflector 2 element beam, MFJ 3element beam or the 24ft EDZ wire(50ohm feed).

I send 100 watts to my Moxon antenna on 13 feet of PVC pipe stuck in a patio umbrella stand in the middle of my back yard. No permanent antennas in my HOA.

Well, right now I'm stationed in South Korea without a license, but when at the home QTH in Mississippi I use an indoor dipole about 30 feet high.  I run QRP in contests and never more than 100 watts.  I am planning a single element antenna application which I've never seen applied before--if I pull it off and it's successful I'll write it up for eHam.

I have a M2 6m HO loop and a 1/4 wave vertical at 35 feet on the roof....so I can switch between them.

My Ranger only runs 25 watts....

I've noticed during the last several openings during June and July, that hams say my 'loop' is a bit louder than the 'vertical'.......I find that interesting. This has been with stations that are West, North and East of me here in Colorado.

100w to an alum. dipole up 20ft oriented E/W. Good enough to work sporadic-E's.
