This may not be news to you in which case Delete the message.

Drew mentions feedline. Especially at 435 MHz, the loss of signal (both received and transmitted) is something to consider. I have a 50 foot tower and a total of about 95 feet of coax between the antenna and the rig.

A good quality coax such as Times Microwave 400 on two meters works well. I put in hard line for 435 MHz as well as a mast mounted preamp because the line loss at 100 ft is significant at UHF and higher frequencies.

Here is a link which will show how many dB of loss you will have at different frequencies for different types of coax. http://www.saarsham.net/coax.html If you have 100 feet of RG-8 coax you will lose half your power in the line. AND the received signal is similarly affected.

You'll get some polarity fading, abd the feedline type and length is very important, but yes, they will work.

I just don’t have room for the 22C and 40CX.

The plan is to use a 3 element 2 meter M2 beam and a 6 element 435 M2

beam on

a Yaesu rotator. I still have my 847 and a 2 meter amp if needed.

Would these antennas work ok for FuneCubeSat?

Thanks,
