SSB Electronics has mast mount preamps that some people prefer over
ARR, that I assume are comparable. But my googling produced a website
that has an error loading.

Not for permanent home station use, but I have used the six UHF
element Arrow as part of a rover in VHF Contest operation:
On the far side of the crossboom.
Had to mount facing sideways as the 3-element 6m beam was too wide to
be street-legal. No rotator (used truck).
Also six element 2m and 18 element 900-MHz loop yagi. Made 81 mile
contact using 15w on 927.50 FM from local 400-foot hill.
The screw-on elements are subject to coming lose with vibration, so
one would need a way to permanently tighten them (lock-tite on threads?).

Subject: [amsat-bb] Arrow Antennas for terrestrial work
Most of the reviews I have seen for the Arrow Antenna dualband yagis are
regarding their use on the satellites, which I think is what they are
mainly made for. Has anyone on the list used one of their dualband
antennas mounted permanently for terrestrial work as well? They do sell a
mounting bracket for permanent mounting to a mast.
Do they seem well made enough to withstand the outside elements for a few
years on end? Do they seem to perform as well as other antennas which have
approximately the same boom size and number of elements?

I have used my Arrow to contact repeaters and for simplex. Works fine. I would replace the studs and screws with stainless and also place bronze wave washers between each element and the boom. But, I don't know about leaving it out in winter weather. Brad Smith KC9UQR
It will be in my prayers
Come back soon.

Best wishes to you and your family on your recovery Bob. You have done so
much good for AMSAT over the many years with all the satellites you have
gotten into orbit. We all appericate your efforts over the years of trying
to get new stuff launched despite all the massive roadblocks in your way of
doing so. Looking forward to PSAT-3 with the SSTV downlink of the earth!

WB4APR will be offline till march.
I found a soft ball size tumor in Oct. After 22 procedures and Dr visits,
they have done ever increasing invasive biopsies and even Cancer center at
Johns Hopkins cannot still identify. And they cannot do anything until they
can identify the type and how to treat it. But now that it is the size of a
football in my lower abdomen, They have scheduled major surgery on Monday to
take it out anyway along with other stuff it is touching.
I must deliver PSAT3 for launch by 28 Feb. Been working full time plus
weekends and holidays but only at 10% body energy level. Its not ready. So
I hope recovery is possible quickly so I can finish. It is identical to
PSAT2 function but without the stupid 5v/4v power mistake.
So, don’t expect any email responses from me till march.
An International Space Station school contact has been planned with participants at Primary School "Jovan Jovanovic Zmaj", Sremska Mitrovica, Serbia on 28 Jan. The event is scheduled to begin at approximately 15:51 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between OR4ISS and YU7BPQ. The contact should be audible over Serbia and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English.
Primary school Jovan Jovanovic Zmaj from Sremska Mitrovica, situated on the left bank of the Sava river in the middle of the region of Srem, is a vibrant, friendly and nurturing school with 65 years of tradition and experience.
The motto of the school based on the lyrics of a famous Serbian poet Jovan Jovanovic Zmaj: "Where I stopped, you carry on", so at school they try to continue the tradition of open-minded, creative, innovative, child-oriented learning and teaching. Based on the past generations' legacy, the school is striving towards shaping cosmopolitan citizens with highly developed tolerance within a multinational society while employing a spectre of techniques to keep up with the modern, high-tech approaches.
The school offers a broad, however, balanced curriculum in a stimulating environment to our 1044 pupils, supported by a wide range of after school clubs and quality school trips. They are always seeking ways to bring to life STEM and foreign language subjects via real-life situations.
This year pupils, teachers, and the HAM operators who support them are as busy as bees, or perhaps as the ISS crew, because they want to talk to the astronauts on the ISS so they are learning about space through various subjects and activities. It is a part of their educational proposal with ARISS. There are fun classes, costumes, Milky Way installation, drawings, maths, history geography and more!
Their friends from the radio amateur club YU7BPQ are helping them with the radio contact! They made a huge antenna! Radio communication is for most students and teachers a new experience. Furthermore, they are learning how to use an amateur radio station! Just imagine how thrilling it is to press the button and hear some noise before you hear the voice behind it! Old school though good stuff!
You can follow all their activities on the project blog page https://022tothemoonandback.zmajsm.edu.rs/home/about-project/
Participants will ask as many of the following questions as time allows:
1. Which planet would you like to visit and why?
2. What manmade wonders can you see from space?
3. What is the furthest spot on the horizon and what can you see around you?
4. Why is the temperature at ISS at constant 38 degrees?
5. What do you do when you cut yourself?
6. What do you do when you can't sleep?
7. What kind of music do you listen to and who chooses it?
8. What do you do for fun?
9. What is your favourite thing about space?
10. Is your space suit comfortable?
11. Is life in space difficult?
12. Can you eat ice cream in space?
13. What is on today's menu?
14. Do you prefer taking off or landing and why?
15. What do you miss most about Earth?
16. Can you see thunders and lightening on Earth?
17. What would you do if you happen to drift away from ISS?
18. What do you do when you get ill?
19. What does it feel like when you get back to Earth?
20. How does the Earth look from above?

Next planned event(s):
Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.
Thank you & 73,
