15m 3/4wave portable gives10m-40m N0MZR 4 weeks, 1 day ago
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!

Part 97 and HR-5852 all mention "Hindrances" to ham radio. I would like to see what the really meaning is as well as what fellow hams also feel are "Hindrances" .............looking for a long list thanks, 73 n0mzr
