Hi Ray,

 Your new dual bander is just great! I was able to adapt it for hand held use for working OU-14 satellite in about one hour with great results.

Assemble the antenna in about 3 minutes, unless you're color blind.

I used a scrap piece of 1 inch PVC pipe as my handle with a 90 degree ell into the mounting structure. I used a 24 inch length of thin wall 3/4 inch PVC pipe that I slid over the coax and the  PL 259 fitting. I held this in place by stuffing a small piece of foam rubber into the PVC. This arrangement easily satisfies the requirement to have the coax run at 90 degrees from the antenna for at least 19 inches. 20 minutes on this max. 

Most of my time was spent programming the Doppler shift frequencies into my IC 706MKIIG, 30 minutes on this, probably less if I had read the manual first.

 I already had the pass predictions run from Sat Scope so I went out on the deck in my backyard with the 706 and a Gel Cell battery and waited for ASO. I used a cheapo compass and just eyeballed the elevation. Wait a few minutes. 

As soon as I heard the FM quiet, I called W6DXO QRZ OU-14 and got a call back almost immediately ... really easy. I have worked OU-14 for the past 4 days with no trouble at all. 

Other observations: 

SWR on 144 is almost flat.. about 1.2:1 across most of the band. 

You don't need a fancy carrying case, just use 2 or 3 rubber bands to hold the elements to the boom for transport or storage. 

No duplexer, just coax and a radio. 

If you want to experiment with the OU-14 satellite and have a radio that will run 144/430 and a 10 foot length of coax, you're ready to go. If you spend more than $4 bucks on this, there is something wrong! 

This is really a well executed design. 

Thanks,  Harry Edwards W6DXO

“Tonight I put your antenna on a shovel handle driven into my landscaping (4 feet above grade), hooked up the cable, turned on my beacon and immediately received an APRS acknowledgement. Needless to say, I’m quite happy with the performance of your antenna.  My transmission problems have been solved.” - - - Mark Pedroia  KF6TYS, 2M Log Periodic

“Just wanted to tell you how satisfied I have been with the 2M Log Periodic antenna. I installed it on a mast on the roof and have it pointed North to access the Berryessa repeater, 90 to 100 miles from my QTH in San Jose. Results have been very good, until I got the LP, I used a J pole and was always marginal, even with 25 watts. Now with the LP, I can have a solid QSO with my friend Jim, W6RWI, in Sacramento with 5 watts.

I appreciate the F/B ratio since the Monterey repeater is on the same frequency (different PL) and I am located about mid-point between the two repeaters.”

“I bought one of your 440 antennas at the Foothill Swap a few months ago and it works GREAT! We’re getting the best bang for the buck , we get great range, bandwidth and directionality with a fleapower xmtr for the uplink video. Uplink works great!” Camera+audio>>LPDA   - - - Frank Hausman, SF

“I have been using your 2M LP as my primary directional antenna for foxhunting. It has good directional characteristics and is the most compact antenna I have found for the gain. This is very important for foxhunting, keep the antenna small and compact. This weekend I used your 440 Log Periodic on the 3^rd harmonic and it worked superbly. I have included your literature in my class notes for the class I teach on foxhunting techniques.” - - - Chris Stewart, KE6MNR  Sebastopole CA

“W7FGQ and I use the your 440 LPs at both ends of a link to our 75 Meter on a daily basis. We see a big improvement over our home built Yagis, like several S units.” - - - R H Hogland W7MZT
