I live in en22ha and the entire portion of the satellite band on 2m is ruined by trucking companies, farmers and custom field services. Feel lucky you do not live in Iowa.Where all your work setting up has been spoiled by unlicensed users. Besides business farm operations on 145.945 , 145.835 and145.845, even the Experimental portion is being invaded. Enjoy while you can !
15m 3/4wave portable gives10m-40m N0MZR on 25/7/14
Portable antennas for camping seem to be a problem for many in my area. Here is what I use. I cut a vertical for 15m ssb phone to 3/4 wave or 32ft. 11in . My radials are 4 ea. at 32ft. 4in. Attached to a base of your choice and fed with 50 ohm coax About 50 ft . On 10m good low angle propagation is acceptable for DX. On 40m you have a 1/4 wave. On 20m it approximates a half wave. Or CW 15m 3/4 wave cut to 33 ft. 3 in. This is a quick one wire up a tree (with my fishing rod and a sinker of adequate weight to fall thru the tree) and 3-4 radials on the ground.(put black tape over one end of each radial . I also use a antenna tuner to extend my other band travels to check in on the 3.970 net. Its simple and often overlooked. This made me a happy camper.

Thanks for the input, here in my locale answers are hard to come by. I am glad we have the ARRL forum. 73 Everett n0mzr

two db-224A's on a repeater tower question N0MZR on 13/7/14
I recently passed by a repeater tower here in Iowa with two DB-224A separated between the tower with at least 1 wave length standoffs , oriented with a north/south pattern. We are wondering what are the advantages of this for repeater use. Will it double the gain of these 4 dipole , 2m antennas in a favored direction without changing the omni pattern that exists with one db-224A. Would it be worth our time to utilize such a setup on our repeater. Also, will losses increase? We have the antennas and will build a standoff to support these if there are positives to such a setup. Thanks for your input!
