After today's improvements, I want more! Ken KG0WX Ken, You might look at the PAR Omniangle OA-50 which sells at AES for $70. It is not a 'gain' antenna per se, but offers a very good omni pattern and is more economical than the other 6 meter loops on the market. If you want gain you could stack a couple of them. To get gain, you have to compromise on the 'economical' criteria as loops tend to show 'about' the same gain as a dipole, however the cost of two loops is less than one beam and a rotor. While I do not own any PAR products (weren't available when I got my AEA Halo or I would've gotten the omniangle!) they are well reviewed in terms of performing as stated and quality of construction. Also, I have communicated with Dale Parfitt, the man behind PAR, through both the newsgroup and a few e-mails and have found him to be both knowledgeable and a decent guy. Good luck & hope to hear you on 6! 73, Howard KE6MAK |

With all the time you spend going up and down stairs to tweak and test this antenna, I'm not really surprised. :-) We eagerly await publication of your book on the Quad Antenna Weight Loss Plan. Stay with it. |

Stay with it. I'll tell ya what - not only have I dropped from 302+ to 209, but I've gone from 1,000 mg Glucophage and 570 units of insulin ($58/1000u) shots per day to no diabetes meds whatsoever. At the same time, my blood sugars have stabilized to the point of being equal to non diabetic numbers, my blood pressure is under control, my cholesterol is improving fast & even my diabetic liver damage has healed itself 60%. All since new years. All I've done is restrict carbs, calories & processed foods plus daily excercise on my Bianchi road race bike (10 miles minimum per day). Eat right & excercise - duuuuuuhhhh.....

| What I need is
| a omnidirectional horizontaly polarized economical gain 6 m antenna. | Anybody got ideas? How about a Turnstile? Even a 6M Turnstile-Reflector should fit inside your 10 foot envelope, but you may not want/need the overhead propagation.

In KS I was in a 1 story apartment but had a very ham friendly landlord. I had a GAP Titan, a Comet GP-15, a 2m/440 vertical and 4 el on 6, 13 el on 2 and 22 el on 440. Things were nice. Then I moved to Denver. I picked the top floor of a 3 story aptartment building, facing away from the mountains (NE corner apt.). I wrapped a 153's dipole made from 22 g clear insulated wire around the building for HF, put a 6m inverted V in the east window and plonked my MFJ "Super High Gain" 2m/440 mag mount on the in the wall A/C unit, which was just below the north window. Not a stellar setup but I could hit any repeater within 25 miles and I was equal to a 20w mobile on HF. After a year of no noise, no TVI, no damages, no cops, no parties and paying the rent on the 1st every month I finally asked the landlord if I could erect antennas on the roof. I explained that I always put up antennas in such a way as they could later be removed with *very* little if any evidence that they had been there. He said OK but no higher than 10 feet above the roof and no holes. I put up a 10 foot mast on a vent pipe mount, holding up a Van Gorden 134' "All Bander" antenna but left the other antennas stay put. Duuuuuuuhhhh.... This morning it hits me - I've got a closet full of coax not being used! 1st, I moved (as an experiment) the 2m/440 mag mount from indoors on the A/C unit to on the roof. I only had to add 4' of coax and on the edge of the roof is steel flashing - perfect for the mag mount! Now I'm hitting repeaters 65 miles away with 5w that I couldn't hit with 50 before and I was recieving at S3-S4 levels. Full scale of course, now. Then, I got more ideas - I took out my old RS mag mount CB ant (the best loaded version they ever made - cost $57 - now cut for 10m) and put it on the roof the same way. It's 18' of stock coax reached just fine. Then came the 6 meter antenna - I grabbed a 50' prefab RS RG58 coax piece and went to the roof with tape, knife, zip ties, rope, etc.... 30 minutes later I had secured it as an inverted V to the 10' mast. I had to re-tune it - it was cut for 50.2 but in the clear it resonated at 53.1! I had to add like 6" of wire to each leg. Man - I thought all the Denver area 6m repeaters were offline....NOT! 53.050 is up! Can't wait till a band opening to see how this 6m ant works now. So, I pulled my head out of $%^$^% and used the equipment on hand. I now have antennas for 80-6, 11-10, 6, 2 & 70cm all up in the clear and that also means no antennas (RF) in the shack. Nice. I'd put a better coax on the 2m/440 ant but it's only 18.2' long so even changing from RG58 to LMR400 probably wouldn't make sense. Heck - it figures out to only 1.3db difference @ 460 mhz. Nah - not worth it I was planning on spending $200 to put up a Diamond X50 on a 5' mast fed with 50' of LMR400 but I don't think so now - I just don't think it would make a difference as I'm hitting all the repeaters within 60 miles on 5w now. So, that's out. I do worry about the 68+' of RG58 I'm running to the 6m inverted V. Loosing 2.2 db on that run @ 52 mhz. Changing to LMR400DB would cut that to 0.6db, gaining 1.6db. Hmmmmm. Maybe.

A Halo?
Popular for 2M mobile until the CBisation with vertically-polarised and channelised FM came along. "Glenn LeBrasseur" wrote in message ... | What I need is | a omnidirectional horizontaly polarized economical gain 6 m antenna. | Anybody got ideas? |
