Jack, Haven’t done it but definitely thinking about it. You may alrady be familiar with the May/June 2014 issue of the AMSAT Journal where Mark Spencer wrote up this arrangement. 73, RayKN2K

I happen to have a pair of the Arrow II handheld SAT antennas available. I wish to use them as a pair set up in crossed polarization. To those who have messed around with various light antenna combinations and have used a pair of Arrows, please let me know your experiences what worked and what did not. Since each antenna has a single 2m and 70cm yagi on it, connecting the 2 element sets will be a little more challenging than one would find for a single band crossed polarized yagi.

Obviously one will be set with the 2m elements vert, the other horizontal. So:

How have you  connected them?

What transmission line harness lengths did you use?

Was RH or LH polarization a consideration?

Was you experiment a satisfactory arrangement?

I am going to take the stock 10W diplexers out of line and use something a little more robust to prevent desense and handle more than 10W.

I am really not interested in hearing about other antennas… I don’t need to be persuaded or dissuaded to do anything else. I have currently have limited resources to put into this, so jumping off the deep end and buying an M2 Leo kit (or even a “crushcraft” pair) is not in the cards.

Thanks in advance for sharing your experience.

Jack,

I use a pair of custom Alaskan Arrows. Solid elements. H/V switched by relays.

Have not tried CP and RH versus LH phasing as more complicated with phasing lines. You might refer to the example from Mark, WA8SME.
